RESUMO

The present field experiment investigated how alibi witnesses react when confronted with camera footage or identification testimony that incriminates an innocent suspect. Under the pretext of a problem-solving study, pairs of participants (N = 109) and confederates worked on an individual task with a dividing wall obstructing their view of each other. When the mobile phone of the experimenter was missing from an adjacent room at the end of the session, all participants confirmed that the confederate had not left the room. After several days, participants returned to the lab for a second session. They were asked to confirm their corroboration, orally and in writing, after learning that the confederate either had been identified from a photograph or was present on camera footage. A control group received no evidence. In this second session, written (but not oral) alibi corroboration was weaker in the incriminating evidence conditions (47%) than the no-evidence condition (81%), as hypothesized. Unexpectedly, corroboration was equally strong in the camera and identification evidence conditions. As expected, alibi corroboration was stronger in session 1 than in session 2 for both camera (89% and 31-46%) and identification evidence conditions (86% and 31-49%). The current findings provide first evidence that camera footage and eyewitness identification testimony can bear on the availability of exculpatory alibi evidence in court and emphasize the need to document incidents of evidence contamination.

RESUMO

Background: Treating disordered feeding at a young age reduces risks of future feeding problems, but not all children profit equally; can we define predictors of a worse prognosis? Objectives: In 252 children, with a mean age of 4; 7 years (SD = 3 years; range 5 months to 17; 10 years), who had undergone behavioral day treatment in the past, several variables were investigated, retrieved from initial consultation (t1) and re-assessed at follow-up (t2). Method: Logistic regressions were carried out with sex, gastro-intestinal problems, refusal of the first nutrition, syndrome/intellectual disability, Down's syndrome, autism spectrum disorder, comorbidity of medical diseases (other than gastro-intestinal problems), restrictive caloric food intake and selective food intake, as the predictor variables from t1, and age-appropriate food intake at t2 as the dependent variable. The potential role of sensory processing problems was reviewed at t2. Results: About 73% had improved towards an age-appropriate food intake. Sex (boys), syndrome/intellectual disability, and a lack of varied nutritional intake at t1 were predictors of a worse prognosis. We found a small, but significant correlation between current selective eating patterns and general sensory processing problems. Conclusion: Feeding disordered children, especially boys, with intellectual disabilities or selective eating patterns are at risk for not achieving an age-adequate food intake at a later age, despite behavioral treatment.

RESUMO

The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) is a risk assessment instrument for adolescents that estimates the risk of multiple adverse outcomes. Prior research into its predictive validity is limited to a handful of studies conducted with the START:AV pilot version and often by the instrument's developers. The present study examines the START:AV's field validity in a secure youth care sample in the Netherlands. Using a prospective design, we investigated whether the total scores, lifetime history, and the final risk judgments of 106 START:AVs predicted inpatient incidents during a 4-month follow-up. Final risk judgments and lifetime history predicted multiple adverse outcomes, including physical aggression, institutional violations, substance use, self-injury, and victimization. The predictive validity of the total scores was significant only for physical aggression and institutional violations. Hence, the short-term predictive validity of the START:AV for inpatient incidents in a residential youth care setting was partially demonstrated and the START:AV final risk judgments can be used to guide treatment planning and decision-making regarding furlough or discharge in this setting.

RESUMO

BACKGROUND: Violent criminal offenders with personality disorders (PD's) can cause immense harm, but are often deemed untreatable. This study aimed to conduct a randomized clinical trial to test the effectiveness of long-term psychotherapy for rehabilitating offenders with PDs. METHODS: We compared schema therapy (ST), an evidence-based psychotherapy for PDs, to treatment-as-usual (TAU) at eight high-security forensic hospitals in the Netherlands. Patients in both conditions received multiple treatment modalities and differed only in the individual, study-specific therapy they received. One-hundred-three male offenders with antisocial, narcissistic, borderline, or paranoid PDs, or Cluster B PD-not-otherwise-specified, were assigned to 3 years of ST or TAU and assessed every 6 months. Primary outcomes were rehabilitation, involving gradual reintegration into the community, and PD symptoms. RESULTS: Patients in both conditions showed moderate to large improvements in outcomes. ST was superior to TAU on both primary outcomes - rehabilitation (i.e. attaining supervised and unsupervised leave) and PD symptoms - and six of nine secondary outcomes, with small to moderate advantages over TAU. ST patients moved more rapidly through rehabilitation (supervised leave, treatment*time: F(5308) = 9.40, p < 0.001; unsupervised leave, treatment*time: F(5472) = 3.45, p = 0.004), and showed faster improvements on PD scales (treatment*time: t(1387) = -2.85, p = 0.005). CONCLUSIONS: These findings contradict pessimistic views on the treatability of violent offenders with PDs, and support the effectiveness of long-term psychotherapy for rehabilitating these patients, facilitating their re-entry into the community.

RESUMO

Background: Young children with disordered feeding may be at increased risk for problematic eating in the future. This retrospective study attempts to identify predictors of later feeding problems. Objectives: Children (N = 236) with disordered feeding, who refrained from behavioral treatment after consultation at a tertiary treatment center for feeding and eating problems were followed-up after, on average, 6 years and 3 months (timepoint 2). Method: Logistic regressions were carried out with characteristics taken at intake (timepoint 1)-sex, pre/dysmaturity, gastro-intestinal disease, history of age-adequate feeding, syndrome/developmental impairment, autism spectrum disorder, comorbidity, age, and several variables of a restrictive- and selective food intake-and duration between timepoint 1 and 2, as predictor variables, and age-appropriate food intake at t2 as the dependent variable. Results: Despite improvement over time, 63% did not reach an age-adequate food intake at t2. Predictors of age-inadequate food intake were: (a) older age; (b) sex (male), (c) longer duration between timepoint 1 and timepoint 2; (d) autism spectrum disorder; (e) selective texture choices and (f) lack of varied nutritional intake. Conclusion: This study shows that most untreated young children's feeding problems do not improve over years. Besides the advice to seek help at an early age, it seems especially recommended to treat (male) children with autism spectrum disorder and selective feeding patterns.

RESUMO

Around the world, an increasing number of people, predominantly women, are choosing to undergo cosmetic surgery-despite the associated health risks. This study aimed to promote a better cross-cultural understanding of the correlates and predictors of favorable attitudes toward cosmetic surgery among women in China (an Eastern country where cosmetic surgery is increasing most rapidly) and the Netherlands (a Western country). Questionnaire data were obtained from 763 adult women; 245 were Chinese women in China (Mage = 29.71), 265 were Chinese women in the Netherlands (Mage = 25.81), and 253 were Dutch women (Mage = 29.22). Facial appearance concerns and materialistic belief were significant predictors of favorable attitudes towards cosmetic surgery for all three cultural groups. Body appreciation was a significant positive predictor among Chinese women in both China and the Netherlands, whereas age and beauty-ideal internalization were significant positive predictors only among Chinese women in China. The findings and their implications are discussed with respect to the characteristics of Chinese culture that could explain the identified differences between Chinese and Dutch women.

RESUMO

The goal of the current study was to investigate individual-level factors associated with job burnout among probation officers (POs) and, specifically, to examine if attitudes toward probationers were linked with job burnout in the context of the recently established probation system in Turkey. Participants (N = 115) were recruited from a probation office in Istanbul. Job burnout was assessed via three components: emotional exhaustion, depersonalization, and professional accomplishment. Results of structural equation modeling indicated that more favorable attitudes toward probationers were related to a lower sense of depersonalization and higher experience of professional accomplishment. However, POs' attitudes toward probationers were not associated with emotional exhaustion. Our findings are discussed in light of the present empirical literature on the contextual factors influential in job burnout. Practical implications for burnout prevention point to the potential effectiveness of working on attitudes among POs toward the people they supervise.

RESUMO

One particular weakness of psychology that was left implicit by Meehl is the fact that psychological theories tend to be verbal theories, permitting at best ordinal predictions. Such predictions do not enable the high-risk tests that would strengthen our belief in the verisimilitude of theories but instead lead to the practice of null-hypothesis significance testing, a practice Meehl believed to be a major reason for the slow theoretical progress of soft psychology. The rising popularity of meta-analysis has led some to argue that we should move away from significance testing and focus on the size and stability of effects instead. Proponents of this reform assume that a greater emphasis on quantity can help psychology to develop a cumulative body of knowledge. The crucial question in this endeavor is whether the resulting numbers really have theoretical meaning. Psychological science lacks an undisputed, preexisting domain of observations analogous to the observations in the space-time continuum in physics. It is argued that, for this reason, effect sizes do not really exist independently of the adopted research design that led to their manifestation. Consequently, they can have no bearing on the verisimilitude of a theory.

RESUMO

Early detection of child abuse risk factors in families of new-born babies is an important task of the public youth health care system in the Netherlands. The Early Risks of Physical Abuse and Neglect Scale (ERPANS) was originally developed in Belgium as an observation scale for public child healthcare nurses. The present longitudinal study is an independent prospective validation of the ERPANS in a Dutch community sample (N = 1257) of families with a new-born. Results showed a commonality of underlying subsets of items belonging to the 'Disturbed parent-child relationship' and 'Psychological problems' factors, but the factor 'Communication problems' of the original ERPANS could not be replicated. We found that parental psychological problems were a significant predictor of family problems, including involvement of child protection authorities, at an average follow-up of 22 months. Parents who reported feeling unloved by their own parents were at higher risk of reports of serious concern to child protection authorities at 22 months after birth. These findings support the utility of at least a subset of the ERPANS items as a screening tool for child abuse risk in preventive public youth health care for new-born babies. Our research adds to a growing body of evidence which points to the importance of parental mental health problems and adverse childhood experiences as precursors to child abuse risk.

RESUMO

Research in perception and recognition demonstrates that a current decision (i) can be influenced by previous ones (i-j), meaning that subsequent responses are not always independent. Experiments 1 and 2 tested whether initial showup identification decisions impact choosing behavior for subsequent showup identification responses. Participants watched a mock crime film involving three perpetrators and later made three showup identification decisions, one showup for each perpetrator. Across both experiments, evidence for sequential dependencies for choosing behavior was not consistently predictable. In Experiment 1, responses on the third, target-present showup assimilated towards previous choosing. In Experiment 2, responses on the second showup contrasted previous choosing regardless of target-presence. Experiment 3 examined whether differences in number of test trials in the eyewitness (vs. basic recognition) paradigm could account for the absence of hypothesized ability to predict patterns of sequential dependencies in Experiments 1 and 2. Sequential dependencies were detected in recognition decisions over many trials, including recognition for faces: the probability of a yes response on the current trial increased if the previous response was also yes (vs. no). However, choosing behavior on previous trials did not predict individual recognition decisions on the current trial. Thus, while sequential dependencies did arise to some extent, results suggest that the integrity of identification and recognition decisions are not likely to be impacted by making multiple decisions in a row.

RESUMO

We investigated the relationships of adolescents' internalizing and externalizing behaviors with their early maladaptive schemas (EMS), coping responses, and schema modes. We focused on EMS related to experiences of disconnection and rejection that comprise vulnerable emotions, such as shame, mistrust, deprivation, abandonment, and isolation/alienation. This cross-sectional study included a total of 699 adolescents (combined clinical and non-referred sample) who were 11 to 18 years old (M = 14.6; SD = 1.6), and of which 45% was male. All participants completed self-report questionnaires on EMS, coping responses, schema modes, and behavior problems. We aimed to clarify the relationships between these variables by testing mediation, moderation, and moderated mediation models. In general, coping responses functioned as mediators rather than moderators in the relationships between EMS and schema modes. Furthermore, EMS regarding experiences of disconnection and rejection were related to both internalizing and externalizing behavior problems, and coping responses and schema modes mediated these effects. In conclusion, although adolescent internalizing and externalizing behavior problems manifest quite differently, they seem related to the same EMS.

RESUMO

This study investigated whether the schema therapy constructs of schema coping and schema modes have val dity in adolescents. We examined the validity and reliability of the Schema Coping Inventory (SCI) and an 80-item version of the Schema Mode Inventory (SMI) in a mixed sample of adolescents. Confirmatory factor analyse showed that the first-order factor structures of the SCI and SMI were replicated, but that the hypothesized higher-order models of the SMI were not confirmed. Instead, we proposed an alternative higher-order model of Internalizing, Externalizing, Overachieving, and Healthy modes. In general, the SCI and SMI scales were able o distinguish the clinical sample from the community sample, and meaningful relationships were found between oping styles, schema modes, and behavior problems. In conclusion, our study supports the theorized relations ips between schema coping styles, schema modes, and behavior, problems in adolescents, and provides initial validation for the SCI and the, 80-item SMI in adolescent populations.

RESUMO

In the eyewitness identification literature, stress and arousal at the time of encoding are considered to adversely influence identification performance. This assumption is in contrast with findings from the neurobiology field of learning and memory, showing that stress and stress hormones are critically involved in forming enduring memories. This discrepancy may be related to methodological differences between the two fields of research, such as the tendency for immediate testing or the use of very short (1-2 hours) retention intervals in eyewitness research, while neurobiology studies insert at least 24 hours. Other differences refer to the extent to which stress-responsive systems (i.e., the hypothalamic-pituitary-adrenal axis) are stimulated effectively under laboratory conditions. The aim of the current study was to conduct an experiment that accounts for the contemporary state of knowledge in both fields. In all, 123 participants witnessed a live staged theft while being exposed to a laboratory stressor that reliably elicits autonomic and glucocorticoid stress responses or while performing a control task. Salivary cortisol levels were measured to control for the effectiveness of the stress induction. One week later, participants attempted to identify the thief from target-present and target-absent line-ups. According to regression and receiver operating characteristic analyses, stress did not have robust detrimental effects on identification performance.

RESUMO

Personality disorders are complex mental health problems, associated with chronic dysfunction in several life domains. Adolescents suffer from these disorders as well. The present study is a naturalistic case study, investigating whether group schematherapy (GST) can be applied to adolescents with personality disorders or personality disorder traits. Four clinically referred patients were included and completed questionnaires on quality of life, symptoms of psychopathology, schema modes, early maladaptive schemas, and schema coping styles. Patients participated in weekly GST sessions complemented by weekly or 2-weekly individual sessions. The parents of the adolescents participated in a separate parent group. From pre- to post-treatment, results demonstrated improvements for some patients in quality of life and symptoms of psychopathology. Changes in a number of modes and schemas were observed in all patients from pre- to post-therapy. In addition to assessing changes from pre- to post-treatment, the current study investigated the temporal changes in modes during therapy as well. Results demonstrated that maladaptive modes decreased, whereas healthy modes increased for all patients across the course of therapy. The present study provides preliminary support for the applicability of GST for adolescents as well as the effectiveness of GST. It is a starting point for further research on this intervention.

RESUMO

PURPOSE: National culture has been shown to play a role in curriculum change in medical schools, and business literature has described a similar influence of organizational culture on change processes in organizations. This study investigated the impact of both national and organizational culture on successful curriculum change in medical schools internationally. METHOD: The authors tested a literature-based conceptual model using multilevel structural equation modeling. For the operationalization of national and organizational culture, the authors used Hofstede's dimensions of culture and Quinn and Spreitzer's competing values framework, respectively. To operationalize successful curriculum change, the authors used two derivates: medical schools' organizational readiness for curriculum change developed by Jippes and colleagues, and change-related behavior developed by Herscovitch and Meyer. The authors administered a questionnaire in 2012 measuring the described operationalizations to medical schools in the process of changing their curriculum. RESULTS: Nine hundred ninety-one of 1,073 invited staff members from 131 of 345 medical schools in 56 of 80 countries completed the questionnaire. An initial poor fit of the model improved to a reasonable fit by two suggested modifications which seemed theoretically plausible. In sum, characteristics of national culture and organizational culture, such as a certain level of risk taking, flexible policies and procedures, and strong leadership, affected successful curriculum change. CONCLUSIONS: National and organizational culture influence readiness for change in medical schools. Therefore, medical schools considering curriculum reform should anticipate the potential impact of national and organizational culture.

RESUMO

In two experiments we tested the choice blindness phenomenon in adolescents aged 11-16 years (Experiment 1, N = 87) and children aged 7-10 years (Experiment 2, N = 117) for the first time. Analogous to previously reported findings with adult participants, we expected to replicate the robust effect in these age groups. Furthermore, we investigated the hypothesis that self-relevance of choices, defined as the extent to which the self is implicated in a choice, moderates the choice blindness effect in adolescents and children. To this end, we directly compared high and low self-relevance conditions. As expected, the choice blindness effect was robust across age groups. Little support was found for the idea that self-relevance moderates the choice blindness effect. Specifically, no effect of self-relevance on choice blindness was found in adolescents, while the findings in the child sample were inconsistent. Different possible interpretations of the results as well as the possible role of ambiguity for the choice blindness effect are discussed.

RESUMO

PURPOSE: Because successful change implementation depends on organizational readiness for change, the authors developed and assessed the validity of a questionnaire, based on a theoretical model of organizational readiness for change, designed to measure, specifically, a medical school's organizational readiness for curriculum change (MORC). METHOD: In 2012, a panel of medical education experts judged and adapted a preliminary MORC questionnaire through a modified Delphi procedure. The authors administered the resulting questionnaire to medical school faculty involved in curriculum change and tested the psychometric properties using exploratory and confirmatory factor analysis, and generalizability analysis. RESULTS: The mean relevance score of the Delphi panel (n = 19) reached 4.2 on a five-point Likert-type scale (1 = not relevant and 5 = highly relevant) in the second round, meeting predefined criteria for completing the Delphi procedure. Faculty (n = 991) from 131 medical schools in 56 countries completed MORC. Exploratory factor analysis yielded three underlying factors-motivation, capability, and external pressure-in 12 subscales with 53 items. The scale structure suggested by exploratory factor analysis was confirmed by confirmatory factor analysis. Cronbach alpha ranged from 0.67 to 0.92 for the subscales. Generalizability analysis showed that the MORC results of 5 to 16 faculty members can reliably evaluate a school's organizational readiness for change. CONCLUSIONS: MORC is a valid, reliable questionnaire for measuring organizational readiness for curriculum change in medical schools. It can identify which elements in a change process require special attention so as to increase the chance of successful implementation.

RESUMO

This study aimed to establish the diagnostic value of multiple lineup decisions made for portrait, body, and profile lineups, including multiple target/suspect choices, rejections, foil choices, and don’t know answers. A total of 192 participants identified a thief and a victim of theft from independent simultaneous target-present or target-absent 6-person portrait, body and profile lineups after watching one of two stimulus films. As hypothesized, multiple target/suspect choices had incriminating value whereas multiple rejections, foil choices, and don’t know answers had mostly exonerating value. For suspect choices, the combination of all three lineup modes consistently elicited high diagnosticities across targets. Combinations of non-suspect choices (rejections, foil choices, or don’t know answers) were less successful and the different combinations showed less consistency in terms of diagnosticity. It was concluded that the use of multiple lineups, such as different facial poses and different aspects of a person should be particularly beneficial in three situations: if a witness only saw the perpetrator from a pose different than the frontal view normally used for lineups; if one or more witnesses saw the perpetrator from more than one perspective; and if different witnesses saw the perpetrator from different perspectives (AU)


El estudio tuvo como objetivo establecer el valor diagnóstico de decisiones múltiples en ruedas fotográficas de identificación de la cara, cuerpo y de perfil, que implican múltiples elecciones del objetivo/sospechoso; rechazos, elecciones de cebos, y respuestas «no sé». Un total de 192 participantes identificaron a un ladrón y a la víctima de un robo en ruedas independientes y simultáneas de perfil, cuerpo o cara de 6 personas con el objetivo presente o ausente. En consonancia con las hipótesis planteadas, elecciones múltiples del objetivo/sospechoso tenían valor incriminatorio mientras que múltiples rechazos, elecciones de cebos y respuestas no sé, generalmente tenían valor exonerante. En las elecciones del sospechoso, la combinación de los tres formatos de ruedas de identificación dio lugar, de modo consistente, a diagnósticos correctos. Las combinaciones de decisiones de no-sospechosos (rechazos, elecciones de cebos, o respuestas no sé) resultaron menos exitosas, al tiempo que las diferentes combinaciones mostraron una menor consistencia en el diagnóstico. Se concluye que el uso de múltiples ruedas de identificación, tales como diferentes poses faciales y diferentes aspectos de una persona deberían ser particularmente beneficiosos en tres situaciones: si un testigo sólo vio al perpetrador desde una posición diferente a la frontal que es la forma de presentación característica de las ruedas; si uno o más testigos vieron al perpetrador desde más de una perspectiva; y si diferentes testigos vieron al perpetrador desde perspectivas diferentes (AU)

RESUMO

BACKGROUND: Prior knowledge activation facilitates learning. Note taking during prior knowledge activation (i.e., note taking directed at retrieving information from memory) might facilitate the activation process by enabling learners to build an external representation of their prior knowledge. However, taking notes might be less effective in supporting prior knowledge activation if available prior knowledge is limited. AIMS: This study investigates the effects of the retrieval-directed function of note taking depending on learners' level of prior knowledge. It is hypothesized that the effectiveness of note taking is influenced by the amount of prior knowledge learners already possess. SAMPLE: Sixty-one high school students participated in this study. A prior knowledge test was used to ascertain differences in level of prior knowledge and assign participants to a low or a high prior knowledge group. METHOD: A 2×2 factorial design was used to investigate the effects of note taking during prior knowledge activation (yes, no) depending on learners' level of prior knowledge (low, high) on mental effort, performance, and mental efficiency. RESULTS: Note taking during prior knowledge activation lowered mental effort and increased mental efficiency for high prior knowledge learners. For low prior knowledge learners, note taking had the opposite effect on mental effort and mental efficiency. CONCLUSIONS: The effects of the retrieval-directed function of note taking are influenced by learners' level of prior knowledge. Learners with high prior knowledge benefit from taking notes while activating prior knowledge, whereas note taking has no beneficial effects for learners with limited prior knowledge.
