The strengths and difficulties questionnaire (SDQ) is a frequently used tool for universal screening of pre-schoolers’ behavioural and emotional problems. However, evidence for its concurrent validity is equivocal and has not been tested in a Māori population. We aimed to evaluate the concurrent validity of the strengths and difficulties questionnaire (SDQ) in Māori pre-schoolers (tamariki), aged 4 and 5. We carried out a prospective study of 225 tamariki (46% female) for whom a recent SDQ was available from the New Zealand Ministry of Health’s Before School Check database. A trained nurse carried out a standardised wellbeing and behavioural assessment for these children. Sensitivity, specificity, positive predictive and negative predictive values were calculated, using optimal total difficulty scale threshold values published for the SDQ (parent version SDQ-P; teacher version SDQ-T). Primary outcome: an assessment-based child referral to Child and Adolescent Mental Health Services or to a Paediatric outpatient service. Secondary outcomes: assessment-based parental referral to a parenting programme and combined referral. The optimal thresholds for child referral were low for the SDQ-P (13) and SDQ-T (7). Child referral SDQ-P: sensitivity 62%, specificity 83%, positive predictive value 0.35, negative predictive value 0.94. Child referral SDQ-T: sensitivity 77%, specificity 78%, positive predictive value 0.31, negative predictive value 0.96. The findings demonstrate optimal threshold values for referral for Māori on the SDQ-P and SDQ-T are much lower when compared to published thresholds (17 vs. 16). Sensitivity values were also low. A surveillance approach for the assessment of psychosocial problems is recommended for pre-schoolers. 相似文献

Women who experience intimate partner violence (IPV) are often mothers. This study seeks to further the understanding of IPV in families, as well as social factors that can prevent violence from occurring. Based on existing literature and theory, we hypothesize that social cohesion and informal social control are associated with lower rates of IPV. To test this theory, we use a total sample of 2,344 mothers with partners surveyed in the Families and Child Wellbeing study and analyze the effects of neighborhood social cohesion and informal social control on reported IPV experiences. This was done by using a negative binomial regression. Findings show that informal social control is associated with lower levels of IPV experiences among mothers with partners. 相似文献

Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event‐related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty‐six demographically similar adolescents (ages 9–14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (n = 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (n = 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (n = 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment‐related effects on these neural systems. 相似文献

We investigated the prevalence of cumulative mild head injury (CMHI) symptoms among college student rugby players pre- and post-season. The players completed a number of neuropsychological tests known to be sensitive to CMHI effects: vocabulary, working memory, motor coordination, and a self-report Post Concussive Symptomology (PCS) checklist. A total of 18 rugby players registered at a South African university were participants (age range 18 to 24 years, SD?=?2.02 years). Data were analysed utilising Fishers Exact Test comparisons of pre- and post-season mean scores. There was significant variability on mean scores between the rugby forwards and backline players in terms of verbal memory and concept formation, cognitive flexibility, working memory, and visual motor-processing speed. Poorer overall scores from the rugby forwards may also be indicative of depression as they reported more insomnia and anger on the PCS than the backline players. 相似文献

Spirituality is a potential area of concern for counseling clients. This study presents the empirical results of a survey completed by 572 counselors to determine if counselors' spiritual beliefs, experiences, or training had an impact on their focus of therapy or self‐perceived competence. A counselor's personal spirituality, spiritual experience, and spirituality training did significantly influence treatment focus as well as self‐perceived competence to counsel a client with spiritual concerns. 相似文献

Using adaptive structuration theory as a framework [DeSanctis, G., & Poole, M. S. (1994). Capturing the complexity in advanced technology use: Adaptive structuration theory. Organization Science, 5(2), 121–147], we examined the influence of organizational context (competitive versus cooperative) and introductory meeting communication medium (face-to-face versus electronic) on the development of trust and collaborative behaviors of dyads communicating electronically. Based on a sample of 208 senior business students operating in computer-mediated (CM) dyads while performing a strategic decision-making simulation, we found that context, introductory communication medium, and time interacted to influence trust and collaborative behaviors. The pattern of development of trust and collaborative behaviors differed for the same introductory communication medium in different context conditions. Further, the level of trust and collaboration for dyad members in the competitive/electronic introductory meeting condition lagged significantly behind those in the other conditions. The findings suggest that introductory face-to-face interaction plays a more important role in facilitating the development of trust and collaboration in a CM environment when the context is competitive. 相似文献

ABSTRACT— What is the nature of early words? Specifically, do infants expect words for objects to refer to kinds or to distinct shapes? The current study investigated this question by testing whether 10-month-olds expect internal object properties to be predicted by linguistic labels. A looking-time method was employed. Infants were familiarized with pairs of identical or different objects that made identical or different sounds. During test, before the sounds were demonstrated, paired objects were labeled with one repeated count-noun label or two distinct labels. Results showed that infants expected objects labeled with distinct labels to make different sounds and objects labeled with repeated labels to make identical sounds, regardless of the objects' appearance. These findings indicate that the 10-month-olds' expectations about internal properties of objects were driven by labeling and provide evidence that even at the beginning of word learning, infants expect distinct labels to refer to different kinds. 相似文献

This study examined the relative weight that hiring managers place on applicants' attractiveness, general mental ability (GMA), and the Big Five personality dimensions in assessing employment suitability for high and low customer contact positions. A sample of 130 managers from 43 hotel properties in the United States and Canada evaluated applicant profiles that varied on these dimensions. The policy capturing results demonstrated that attractiveness does impact employment suitability ratings across positions. However, attractiveness is valued less than GMA and conscientiousness. The attractiveness weight was greater in the evaluation of high customer contact positions, suggesting that attractiveness may be perceived as more job‐relevant for positions where employees interact extensively with people outside the organization. These findings are discussed along with implications for practice and future research attention. 相似文献

The “false-hope syndrome” suggests that unrealistic expectations are responsible for the cycle of repeated failure and renewed efforts at self-change characterizing many self-changers. Our hypotheses were that: (1) committing to a particular self-change task would inflate initial expectations, (2) participants would be unsuccessful relative to their expectations, and (3) more elevated expectations would lead to more negative outcomes. Participants were randomly assigned to either increase their physical activity or reduce their stress through meditating or were assigned to a no-change control group. In accordance with Hypotheses 1 and 2, exercise participants had more positive expectations about their resolutions immediately after committing to them, and both exercise and meditation participants were unsuccessful relative to their expectations. With respect to Hypothesis 3, however, having more positive expectations about one's resolution did not predict a worse outcome. 相似文献

The present study examined the association between high status social positions in early adolescence and both overt and relational aggression. A sample of 234 sixth graders (132 girls, 102 boys) completed peer nominations assessing aggression, social centrality, and coolness. Data analyses were based on all sixth graders who received peer nominations, for a total sample size of 417 students (224 girls, 193 boys). Hierarchical linear modeling was used to examine both within-peer group differences and between-peer group differences. Results indicated relational aggression was related to higher overall social centrality and being nominated as cool even when controlling for overt aggression. Overt aggression appeared to be related to higher overall social centrality and being nominated as cool, but this relationship was much weaker when relational aggression was controlled. Although girls used relational aggression more often and boys used overt aggression more often, the use of relational aggression by either gender was related to membership in high status peer groups and high status within the peer group. Implications of the findings and suggestions for future research are discussed. 相似文献
