In the application of range of motion (ROM) tests there is little agreement on the number of repetitions to be measured and the number of preceding warm-up protocols. In stretch training a plateau in ROM gains can be seen after four to five repetitions. With increasing number of repetitions, the gain in ROM is reduced. This study examines the question of whether such an effect occurs in common ROM tests. Twenty-two healthy sport students (10 m/12 f.) with an average age of 25.3 ± 1.94 years (average height 174.1 ± 9.8 cm; weight 66.6 ± 11.3 kg and BMI 21.9 ± 2.0 kg/cm2) volunteered in this study. Each subject performed five ROM tests in a randomized order—measured either via a tape measure or a digital inclinometer: Tape measure was used to evaluate the Fingertip-to-Floor test (FtF) and the Lateral Inclination test (LI). Retroflexion of the trunk modified after Janda (RF), Thomas test (TT) and a Shoulder test modified after Janda (ST) were evaluated with a digital inclinometer. In order to show general acute effects within 20 repetitions we performed ANOVA/Friedman-test with multiple comparisons. A non-linear regression was then performed to identify a plateau formation. Significance level was set at 5%. In seven out of eight ROM tests (five tests in total with three tests measured both left and right sides) significant flexibility gains were observed (FtF: p < 0.001; LI-left/right: p < 0.001/0.001; RF: p = 0.009; ST-left/right: p < 0.001/p = 0.003; TT-left: p < 0.001). A non-linear regression with random effects was successfully applied on FtF, RF, LI-left/right, ST-left and TT-left and thus, indicate a gradual decline in the amount of gained ROM. An acute effect was observed in most ROM tests, which is characterized by a gradual decline of ROM gain. For those tests, we can state that the acute effect described in the stretching literature also applies to the performance of typical ROM tests. Since a non-linear behavior was shown, it is the decision of the practitioner to weigh up between measurement accuracy and expenditure. Researchers and practitioners should consider this when applying ROM assessments to healthy young adults.
In recent decades, the assessment of instructional quality has grown into a popular and well-funded arm of educational research. The present study contributes to this field by exploring first impressions of untrained raters as an innovative approach of assessment. We apply the thin slice procedure to obtain ratings of instructional quality along the dimensions of cognitive activation, classroom management, and constructive support based on only 30 s of classroom observations. Ratings were compared to the longitudinal data of students taught in the videos to investigate the connections between the brief glimpses into instructional quality and student learning. In addition, we included samples of raters with different backgrounds (university students, middle school students and educational research experts) to understand the differences in thin slice ratings with respect to their predictive power regarding student learning. Results suggest that each group provides reliable ratings, as measured by a high degree of agreement between raters, as well predictive ratings with respect to students’ learning. Furthermore, we find experts’ and middle school students’ ratings of classroom management and constructive support, respectively, explain unique components of variance in student test scores. This incremental validity can be explained with the amount of implicit knowledge (experts) and an attunement to assess specific cues that is attributable to an emotional involvement (students).
High-intensity functional training (HIFT) has become a popular method in the sports and fitness sector. In contrast to unimodal approaches such as strength or endurance training, it has been hypothesized to induce concurrent adaptations in multiple markers of motor function. However, to date, the effectiveness of HIFT in this regard has not been studied. The present systematic review quantified the chronic effects of HIFT on motor function in healthy individuals. A multilevel meta-analysis with a robust random effects meta-regession model was used to pool the standardized mean differences (SMD) between (a) HIFT and (b) no-exercise (NEX) as well as conventional endurance, resistance and balance training for outcomes of muscle strength, endurance capacity and balance. The influence of possible effect modifiers such as program duration, session duration, age or sex was examined in a moderator analysis. Seventeen papers with moderate to high methodological quality (PEDro scale) were identified. Compared to NEX, HIFT had small to moderate positive effects on endurance capacity (SMD: 0.42, 95% CI 0.07–0.78, p = 0.03) and strength (0.60, 95% CI 0.02–1.18, p = 0.04) but no effect on balance (SMD: − 0.10, 95% CI − 1.13 to 0.92, p = 0.42). Regarding endurance, HIFT showed similar effectiveness as moderate-intensity endurance training (SMD: − 0.11, 95% CI − 1.17 to 0.95, p = 0.75) and high-intensity interval endurance training (SMD: − 0.15, 95% CI − 1.4 to 1.1, p = 0.66). No comparisons of HIFT vs. classical resistance or balance training were found. Moderator analyses revealed no influence of most effect modifiers. However, regarding endurance, females seemed to respond more strongly to HIFT in the comparison to NEX (p < .05). HIFT appears to represent an appropriate method to induce chronic improvements in motor function. While being superior to NEX and non-inferior to endurance training, current evidence does not allow a comparison against resistance and balance training. The impact of possible effect moderators should be further elucidated in future research.
Misconceptions about scientific concepts often prevail even if learners are confronted with conflicting evidence. This study tested the facilitative role of surprise in children’s revision of misconceptions regarding water displacement in a sample of German children (N = 94, aged 6–9 years, 46% female). Surprise was measured via the pupil dilation response. It was induced by letting children generate predictions before presenting them with outcomes that conflicted with their misconception. Compared to a control condition, generating predictions boosted children’s surprise and led to a greater revision of misconceptions (d = 0.56). Surprise further predicted successful belief revision during the learning phase. These results suggest that surprise increases the salience of a cognitive conflict, thereby facilitating the revision of misconceptions.
Positive psychological coaching (PPC) has emerged as a popular “paradigm” for practitioners interested in the professional development of people. A recent review consolidated the literature on PPC and produced a 5-phase positive psychological coaching model aimed at facilitating professional growth. However, little is known about practically operationalizing each phase of the coaching process (i.e., how to facilitate each phase and which underlying tools and techniques could be employed to do so). As such, the purpose of this systematic review was to address this limitation by (a) determining which coaching tools and techniques are proposed within the coaching literature and (b) classifying the identified tools and techniques into the respective phases of PPC model. The investigation used a two-step approach by conducting a systematic literature review (to identify various PPC tools/techniques) followed by an iterative heuristic classification process (to assign these PPC tools/techniques to a known PPC model). The systematic literature review resulted in 24 peer-reviewed publications on positive psychological coaching, providing 117 different coaching tools that could be condensed into 18 overarching coaching techniques. The iterative classification process showed that most techniques and tools are useful in at least two phases. Interestingly, experts still vary in opinion on the timing and application of these specific techniques and tools within the positive psychological coaching process. This study provides researchers and practitioners with practical guidelines to facilitate a positive psychological coaching process.
The COVID-19 lockdown has significantly disrupted the higher education environment within the Netherlands and led to changes in available study-related resources and study demands of students. These changes in study resources and study demands, the uncertainty and confusion about educational activities, the developing fear and anxiety about the disease, and the implementation of the COVID-19 lockdown measures may have a significant impact on the mental health of students. As such, this study aimed to investigate the trajectory patterns, rate of change, and longitudinal associations between study resources–demands and mental health of 141 university students from the Netherlands before and during the COVID-19 lockdown. The present study employed a longitudinal design and a piecewise latent growth modeling strategy to investigate the changes in study resources and mental health over a 3 month period. The results showed that moderate levels of student resources significantly decreased before, followed by a substantial rate of increase during, lockdown. In contrast, study demands and mental health were reported to be moderate and stable throughout the study. Finally, the growth trajectories of study resources–demands and mental health were only associated before the lockdown procedures were implemented. Despite growing concerns relating to the negative psychological impact of COVID-19 on students, our study shows that the mental health during the initial COVID-19 lockdown remained relatively unchanged.
In sports and clinical settings, roller massage (RM) interventions are used to acutely increase range of motion (ROM); however, the underlying mechanisms are unclear. Apart from changes in soft tissue properties (i.e., reduced passive stiffness), neurophysiological alterations such as decreased spinal excitability have been described. However, to date, no study has investigated both jointly. The purpose of this trial was to examine RM’s effects on neurophysiological markers and passive tissue properties of the plantar flexors in the treated (ROLL) and non-treated (NO- ROLL) leg. Fifteen healthy individuals (23 ± 3 years, eight females) performed three unilateral 60-s bouts of calf RM. This procedure was repeated four times on separate days to allow independent assessments of the following outcomes without reciprocal interactions: dorsiflexion ROM, passive torque during passive dorsiflexion, shear elastic modulus of the medial gastrocnemius muscle, and spinal excitability. Following RM, dorsiflexion ROM increased in both ROLL (+19.7%) and NO-ROLL (+13.9%). Similarly, also passive torque at dorsiflexion ROM increased in ROLL (+15.0%) and NO-ROLL (+15.2%). However, there were no significant changes in shear elastic modulus and spinal excitability (p > 0.05). Moreover, significant correlations were observed between the changes in DF ROM and passive torque at DF ROM in both ROLL and NO-ROLL. Changes in ROM after RM appear to be the result of sensory changes (e.g., passive torque at DF ROM), affecting both rolled and non-rolled body regions. Thus, therapists and exercise professionals may consider applying remote treatments if local loading is contraindicated.
Working memory capacity (WMC) and fluid intelligence (Gf) are highly correlated, but what accounts for this relationship remains elusive. Process-overlap theory (POT) proposes that the positive manifold is mainly caused by the overlap of domain-general executive processes which are involved in a battery of mental tests. Thus, executive processes are proposed to explain the relationship between WMC and Gf. The current study aims to (1) achieve a relatively purified representation of the core executive processes including shifting and inhibition by a novel approach combining experimental manipulations and fixed-links modeling, and (2) to explore whether these executive processes account for the overlap between WMC and Gf. To these ends, we reanalyzed data of 215 university students who completed measures of WMC, Gf, and executive processes. Results showed that the model with a common factor, as well as shifting and inhibition factors, provided the best fit to the data of the executive function (EF) task. These components explained around 88% of the variance shared by WMC and Gf. However, it was the common EF factor, rather than inhibition and shifting, that played a major part in explaining the common variance. These results do not support POT as underlying the relationship between WMC and Gf.
The strengths use scale: psychometric properties, longitudinal invariance and criterion validity
(2021)
Strengths use is an essential personal resource to consider when designing higher-educational programs and interventions. Strengths use is associated with positive outcomes for both the student (e.g., study engagement) and the university (e.g., academic throughput/performance). The Strengths Use Scale (SUS) has become a popular psychometric instrument to measure strengths use in educational settings, yet its use has been subjected to limited psychometric scrutiny outside of the U.S. Further, its longitudinal stability has not yet been established. Given the wide use of this instrument, the goals of this study were to investigate (a) longitudinal factorial validity and the internal consistency of the scale, (b) its equivalence over time, and (c) criterion validity through its relationship with study engagement over time. Data were gathered at two-time points, 3 months apart, from a sample of students in the Netherlands (n = 360). Longitudinal confirmatory factor analyses showed support for a two-factor model for overall strengths use, comprised of Affinity for Strengths and Strengths Use Behaviors. The SUS demonstrated high levels of internal consistency at both the lower- and upper bound limits at both time points. Further, strict longitudinal measurement invariance was established, which confirmed the instrument's temporal stability. Finally, criterion validity was established through relating strengths use to study engagement at different time stamps. These findings support the use of the SUS in practice to measure strengths use and to track the effectiveness of strengths use interventions within the higher education sector.
Specifying accurate informative prior distributions is a question of carefully selecting studies that comprise the body of comparable background knowledge. Psychological research, however, consists of studies that are being conducted under different circumstances, with different samples and varying instruments. Thus, results of previous studies are heterogeneous, and not all available results can and should contribute equally to an informative prior distribution. This implies a necessary weighting of background information based on the similarity of the previous studies to the focal study at hand. Current approaches to account for heterogeneity by weighting informative prior distributions, such as the power prior and the meta-analytic predictive prior are either not easily accessible or incomplete. To complicate matters further, in the context of Bayesian multiple regression models there are no methods available for quantifying the similarity of a given body of background knowledge to the focal study at hand. Consequently, the purpose of this study is threefold. We first present a novel method to combine the aforementioned sources of heterogeneity in the similarity measure ω. This method is based on a combination of a propensity-score approach to assess the similarity of samples with random- and mixed-effects meta-analytic models to quantify the heterogeneity in outcomes and study characteristics. Second, we show how to use the similarity measure ω as a weight for informative prior distributions for the substantial parameters (regression coefficients) in Bayesian multiple regression models. Third, we investigate the performance and the behavior of the similarity-weighted informative prior distribution in a comprehensive simulation study, where it is compared to the normalized power prior and the meta-analytic predictive prior. The similarity measure ω and the similarity-weighted informative prior distribution as the primary results of this study provide applied researchers with means to specify accurate informative prior distributions.
Empathie ist ein mehrdimensionales psychologisches Konstrukt, das aus verschiedenen Facetten besteht (Decety & Ickes, 2011). Es ist anzunehmen, dass Empathie ein wichtiger Mechanismus ist, um Menschen miteinander zu verbinden und eine Gruppenkohäsion möglich zu machen (Rameson & Lieberman, 2009). Neben der Fähigkeit die Erlebenswelt des Gegenübers mit eigenen mentalen Repräsentationen nachzuvollziehen, werden dadurch Emotionen ausgelöst, die denen des Gegenübers sehr ähnlich sind. Gleichzeitig unterscheidet sich dieses Gefühlserleben aber beispielsweise von reiner Gefühlsansteckung, da eine Selbst-Andere Differenzierung stattfindet und in einer empathischen Episode immer im Vordergrund steht, dass man sich aufgrund der Gefühle des anderen so fühlt (Altmann, 2015). Hier spielt Imitation eine wichtige Rolle, wenn es darum geht, die Erlebenswelt der anderen Person zu erfassen (Meltzoff & Decety, 2003). Besonders auch bei Lehrkräften zeigt sich eine Wichtigkeit von empathischem Handeln und Verstehen (Tausch & Tausch, 2008). In verschiedenen Studien zeigten sich positive Effekte von Empathie auf die Schülerschaft und die Unterrichtsqualität. Die SchülerInnen trauen sich mehr, es herrscht weniger Angst im Klassenzimmer und die Qualität der Unterrichtsbeiträge steigt (vgl. Tausch & Tausch, 1998). Empathie selbst besteht aus State- und Trait-Anteilen, so dass zumindest Teile davon trainierbar sind (Butters, 2010). Eine potentielle Möglichkeit um Empathie zu fördern scheint das Lehr-Lern-Format Service Learning (SL) darzustellen. Hierbei handelt es sich um ein Veranstaltungskonzept, bei dem ein meist fachlicher, akademischer Inhalt mit einem ehrenamtlichen Engagement außerhalb der Universität verknüpft wird (Reinders, 2016). Forschung aus dem angloamerikanischen Raum weist darauf hin, dass Empathie durch derartige Formate gefördert werden kann (Lundy, 2007; Wilson, 2011). Da die meisten Messverfahren von Empathie auf Selbstauskunft basieren und damit nur indirekt Anteile wie das affektive Mitschwingen abbilden können, war es Teil dieser Arbeit im ersten Schritt einen objektiven, videobasierten Test zu entwickeln, der dann mit anderen Verfahren zur Messung eingesetzt werden sollte. In zwei ExpertInnen-Befragungen wurden aus einem Pool von Videosequenzen mit Unterrichtssituationen insgesamt zehn Videoclips mit jeweils vier Items und zugehörigen Antwortoptionen extrahiert. In einer darauf folgenden Validierung mit Studierenden der Goethe-Universität (N = 112) wurden diese Vignetten mit verschiedenen Verfahren zur Messung von Empathie gemeinsam erhoben und die Zusammenhänge analysiert. Die Reliabilitäten der drei Testscores bewegten sich in den beiden gebildeten Testversionen zwischen Cronbachs α = .53 (Verhaltens-Score der Testversion 1) und α = .76 (Intensitäts-Score der Testversion 2). Es zeigten sich zu allen Fragebögen erwartungskonforme Zusammenhänge von kleinen bis mittleren Effekten. Die Itemschwierigkeiten bei den meisten Items lagen zwischen 50 und 65, die Trennschärfen zwischen .18 und .70.
Im nächsten Entwicklungsschritt wurden die Vignetten in neu zusammengestellten Testversionen nur Lehramtsstudierenden (N = 41) vorgelegt und zusätzlich Videoaufnahmen der Gesichter der ProbandInnen gemacht, um sie mit Face-Reader zu analysieren und die Facette Mitschwingen abzubilden. Die Reliabilitäten der Testversionen lagen mit einem neuen Scoring nun zwischen α = .24 (Emotionserkennungs-Score Prä-Testversion) und
α = .57 (Intensitäts-Score Prä-Testversion) sowie zwischen α = .10 (Emotionserkennungs-Score Post-Testversion) und α = .77 (Intensitäts-Score Post-Testversion). Auch die Schwierigkeiten und Trennschärfen änderten sich nach Adaptieren des Scorings und bewegten sich in beiden Testversionen nun von 30 bis 89 (Schwierigkeit) und von .0 bis .5 (Trennschärfe). Die Face-Reader Analysen zeigten nur in Teilen kongruente Emotionen mit den Selbstauskunftsdaten bzw. den eingeschätzten Intensitäten in den Videosequenzen, dann allerdings mittlere bis große Effekte, so dass in Teilen von einem affektiven Mitschwingen ausgegangen werden kann. Da sich die internen Konsistenzen im Vergleich zur Validierung verschlechterten, wurden die Zusammensetzungen der Testversionen für den Praxiseinsatz wieder auf die Validierungs-Versionen umgestellt.
Im Praxiseinsatz wurden Lehramtsstudierende in SL und Non-SL-Veranstaltungen rekrutiert und miteinander verglichen. Insgesamt nahmen N = 68 Personen an drei Messzeitpunkten teil (n = 30 in SL und n = 38 in Non-SL-Seminaren). Die Analysen zeigten, dass es zwischen den Gruppen keine signifikanten Unterschiede in den genutzten Instrumenten gab. Auch über die Zeit gab es nach der Bonferroni-Korrektur nur einen signifikanten Effekt (F (2,52) = 6.57, p = .003, η2 = .20). Es ist anzunehmen, dass diese Ergebnisse vor allem auf methodische Einschränkungen und Verbesserungsmöglichkeiten des entwickelten Testverfahrens zurückzuführen sind. Weitere Möglichkeiten werden diskutiert.
Dual-task paradigms encompass a broad range of approaches to measure cognitive load in instructional settings. As a common characteristic, an additional task is implemented alongside a learning task to capture the individual’s unengaged cognitive capacities during the learning process. Measures to determine these capacities are, for instance, reaction times and interval errors on the additional task, while the performance on the learning task is to be maintained. Opposite to retrospectively applied subjective ratings, the continuous assessment within a dual-task paradigm allows to simultaneously monitor changes in the performance related to previously defined tasks. Following the Cognitive Load Theory, these changes in performance correspond to cognitive changes related to the establishment of permanently existing knowledge structures. Yet the current state of research indicates a clear lack of standardization of dual-task paradigms over study settings and task procedures. Typically, dual-task designs are adapted uniquely for each study, albeit with some similarities across different settings and task procedures. These similarities range from the type of modality to the frequency used for the additional task. This results in a lack of validity and comparability between studies due to arbitrarily chosen patterns of frequency without a sound scientific base, potentially confounding variables, or undecided adaptation potentials for future studies. In this paper, the lack of validity and comparability between dual-task settings will be presented, the current taxonomies compared and the future steps for a better standardization and implementation discussed.
School psychologists are asked to systematically evaluate the effects of their work to ensure quality standards. Given the different types of methods applied to different users of school psychology measuring the effects of school psychological services is a complex task. Thus, the focus of our scoping review was to systematically investigate the state of past research on the measurement of the effects of school psychological services published between 1998 and 2018 in eight major school psychological journals. Of the 5,048 peer-reviewed articles published within this period, 623 were coded by two independent raters as explicitly refering to school psychology or counseling in the school context in their titles or abstracts. However, only 22 included definitions of effects of school psychological services or described outcomes used to evaluate school psychological services based on full text screening. These findings revealed that measurement of the effects of school psychological services has not been a focus of research despite its' relevance in guidelines of school psychological practice.
The role of orthographic knowledge for reading performance in German elementary school children
(2021)
Reading is crucial for successful participation in the modern world. However, 3-8% (e.g., Moll et al., 2014) of children in elementary school age show reading difficulties, which can lead to limited education and enhance risks of social and financial disadvantages (Valtin, 2017). Therefore, it is important to identify reading relevant components (Tippelt & Schmidt-Hertha, 2018). In this context, especially phonological awareness (i.e., awareness of the sound structure of the language) and naming speed (i.e., fast and automatized retrieval of information) were identified as significant components for reading skills (e.g., Georgiou et al., 2012; Landerl & Thaler, 2006; Vellutino, Fletcher, Snowling, & Scanlon, 2004). One further component, which is of growing interest to the recent research, is orthographic knowledge. It comprises the knowledge about the spelling of specific words (word-specific orthographic knowledge) and about legal letter patterns (general orthographic knowledge; Apel, 2011).
Previous research focused predominantly on examining the role of orthographic knowledge on basic reading level, including word identification and word meaning (Conrad et al., 2013; Rothe et al., 2015). The relationship between orthographic knowledge and reading comprehension as the core objective of reading, including understanding of the relationship between words within a sentence as well as building a coherence between sentences (Perfetti et al., 2005), was on the contrary scarcely the object of research. The first goal of this dissertation is, therefore, to provide a remedy by investigating the role of orthographic knowledge on higher reading processes (sentence- and text-level). The scarce body of research investigating children with reading difficulties provide a mixed result pattern (e.g., Ise et al., 2014). Therefore, this dissertation aims at clarifying the influence of orthographic knowledge on word-, sentence-, and text-level in children without and with reading difficulties.
A thorough understanding of reading relevant components is also important for conception of interventions aiming at individual reading performance improvements in order to prevent school failure. One promising approach to help children to overcome their reading difficulties is a text-fading based reading training. During this procedure, reading material is faded out letter by letter in reading direction (i.e., in German from left to right; Breznitz & Nevat, 2006). The aim of this manipulation is to prompt the individual to read faster than usual, resulting in reading rate and comprehension improvements (e.g., Nagler et al., 2015). However, the underlying mechanisms leading to improvements of reading performance are still unclear. Considering previous findings showing orthographic skills to influence training outcomes (Berninger et al., 1999), and also word reading performance after a reading intervention (Stage et al., 2003), it seems plausible to include orthographic knowledge when investigating potential training effects. Therefore, this dissertation aims at investigating the predictive value of orthographic knowledge for comprehension performance during the text-fading based reading training.
In order to answer the first research question, two empirical papers are implemented (see Appendix A: Zarić et al., 2020 and Appendix B: Zarić & Nagler, 2021), which investigate the role of orthographic knowledge for reading at word-, sentence-, and text-level in German school children without and with reading difficulties. The study by Zarić et al. (2020) examines the incremental predictive value for explained reading variance of both word-specific and general orthographic knowledge in relation to variance amount explained by general intelligence and phonological awareness. For this purpose, data from 66 German third-graders without reading difficulties were analyzed. Correlation and multiple regression analyses have shown that word-specific and general orthographic knowledge contribute a unique significant amount to the variance of reading comprehension on word-, sentence-, and text-level, over and above the explained variance by general intelligence and phonological awareness. In order to answer the question whether word-specific and general orthographic knowledge also explain variance in children with poor reading proficiency, in addition to established predictors phonological awareness and naming speed, the data from 103 German third-graders with reading difficulties were analyzed in a second study (Zarić & Nagler, 2021). The analyses revealed that word-specific and general orthographic knowledge explain a unique significant amount of the variance of reading on word- and sentence-level. On text-level, these two components did not explain a significant amount of unique variance. Here, only phonological awareness was shown to be a significant predictor. The results indicate that the knowledge about the spelling of specific words (word-specific orthographic knowledge) and the knowledge about legal letter patterns (general orthographic knowledge) contribute to reading comprehension on word-level. Following the assumptions, for instance, of the Lexical Quality Hypothesis (Perfetti & Hart, 2002) high-quality orthographic representations are considered to be important for higher reading processes, such as comprehension.

It is increasingly recognized that neuroscience has not delivered the revolutionary clinical possibilities for psychiatry that had been promised. Explanations differ, however: some proponents emphasize the divide between biopsychosocial psychiatry and mechanistic neurology. Others rely on further basic experimental neuroscience as only the most elementary level of explanation will allow us to fully understand and treat mental disorders. From a clinical-neuropsychological perspective, I shall argue that both views are mistaken. Diagnosis and treatment of neurological diseases demands a biopsychosocial perspective similar to psychiatry. Acknowledging this might help to bring both disciplines together and improve clinical outcome.
Bisherige Forschungsergebnisse zeigen, dass auch Frauen sexuellen Kindesmissbrauch begehen und somit eine potentielle Gefahr für das Kindeswohl darstellen können. Aus Deutschland liegen bisher nur regionale oder Studien mit geringer Stichprobengröße vor. Die vorliegende Studie verfolgt das Ziel, eine umfassende Bestandserhebung des sexuellen Kindesmissbrauchs durch Frauen in Deutschland zu dokumentieren. Im Rahmen der vorliegenden Untersuchung wurden zum ersten Mal bundesweit Strafakten von 465 pädokriminellen Frauen ausgewertet, die in den letzten 30 Jahren nach §§174, 176, 180 oder 182 des StGB verurteilt wurden. Die standardisierte Analyse umfasst 185 Variablen und 54 selbst definierte Skalen. Die Ergebnisse zeigen, dass eine pädokriminelle Frau durchschnittlich 33 Jahre alt ist, zumeist in einer Ehe in einer Kleinstadt lebt und häufig keiner beruflichen Tätigkeit nachgeht. Sie ist eine Mittäterin, handelt überwiegend aus Abhängigkeit zu ihrem männlichen Komplizen heraus, zu dem sie eine intime Beziehung pflegt und missbraucht mehrheitlich weibliche Opfer (Verhältnis fast 2:1). Beinahe die Hälfte der 614 Opfer, zu denen Informationen vorlagen, waren leibliche Kinder der Täterinnen und rund jedes sechste Kind stammte vom männlichen Mittäter.
