物质相关线索对成瘾者反应抑制的影响

成瘾者失控的物质寻求和使用与反应抑制的关系密切。很多研究在物质相关线索情境中探讨了这一关系。物质相关线索既可受到自动的注意加工, 又可诱发非自动的趋近动机状态。因此, 它们可能通过刺激驱动和状态依赖两种方式消耗有限的认知资源从而影响反应抑制, 这在成瘾行为的发展和维持中起到重要作用。未来需要在揭示其神经机制、明确物质使用动机或态度的调节、采用真实情境进行研究, 以及开发有效的干预方法等几个方面开展研究。     

Effects of Intensive Behavioral Treatment for Children With Varying Levels of Conduct Problems and Callous-Unemotional Traits

The purpose of this study was to examine whether callous–unemotional (CU) traits moderated the effects of intensive behavior therapy in elementary school-age children with varying levels of conduct problems (CP). Both treatment response (magnitude of change between pre- and posttreatment) and treatment outcomes (likelihood of normalization from treatment) were examined. Participants were 67 children (n = 49 boys, M_age = 9.6 years) with varying levels of CP and CU who participated in an intensive 8-week summer treatment program (STP) in which behavior therapy was delivered to children in recreational and classroom settings and to parents via weekly parent training sessions. Effects of treatment were measured using parent and teacher ratings of oppositional defiant disorder (ODD), conduct disorder (CD), callous behavior, and impairment. Results showed that CU moderated treatment effects for CD and callous behavior but not ODD or impairment. The moderating effects showed some evidence that participants with high CP and high CU before treatment had better treatment responses (larger change between pre- and posttreatment) but worse treatment outcomes (lower likelihood of normalization after treatment). These results suggest that intensive treatment, such as the STP, may be necessary but not sufficient for children with CP and CU traits.     

Behavioral skills training in scent detection research: Interactions between trainer and animal behavior

Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another.     

Youth Needs at Intake into Trauma‐Informed Group Homes and Response to Services: An Examination of Trauma Exposure,Symptoms, and Clinical Impression

Trauma‐informed care is recommended to improve the quality of group home services for youth. Youth exposure to trauma and associated symptoms are important factors involved in making the clinical impression that determines treatment services. This study considered three dimensions of trauma (exposure, symptoms, and clinical impression) to determine associations with behavioral incidents of youth in trauma‐informed group homes and how trauma was related to changes in psychopathology from intake to discharge. Archival records of youth (N = 1,096), age 9–18 (M = 15.7 years) who received services from January 2013 to December 2017, and departed the program were used. Statistical procedures included hierarchical linear modeling and analysis of covariance. Results indicated trauma symptoms predicted emotional problems and self‐injurious behavior. Youth in high‐ and low‐trauma groups both showed decreases in behavioral incidents and psychopathology, but clinical impression of trauma moderated the change in emotional problems from intake to discharge. Youth deemed by clinicians to have lower trauma (based on history of maltreatment and expression of trauma symptoms) had greater decrease in emotional problems from admission to discharge. Limitations and implications for further research on implementation and effectiveness of trauma‐informed models are discussed.     

Factor analysis and validation of a self-report measure of impaired fear inhibition

Difficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive–behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire (FIQ), a self-report measure of fear inhibition abilities. We assess the FIQ’s factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whilst controlling for anxious symptoms, suggests that the FIQ represents a valid and unique measure of fear inhibition abilities. The FIQ might be used to assess more ecologically valid fear inhibition problems particularly amongst people who have or who are at risk of anxiety diagnoses.     

Influence of Attachment Style on Sexual Abuse Survivors' Posttraumatic Growth

This study investigated the directional relationship between adults' (N = 292) attachment styles and perceived impact of child sexual abuse with their experience of posttraumatic growth (PTG). Structural equation modeling results identified that attachment style served as a partial mediator between trauma and PTG scores, with the mediating effect contributing to 8% of the variance in the presence of PTG (p < .05; standardized coefficient = ?.31).     

Attitudes related to child sexual abuse: scale construction and explorative study among psychologists

A Child Sexual Abuse Attitude and Belief Scale was constructed and then answered by 242 child psychologists. Four CSA related attitude and belief subscales were identified through confirmatory factor analysis: (1) The Disclosure subscale reflecting favouring a disclosure at any cost; (2) The Pro-Child subscale reflecting unconditional belief in children's reports; (3) The Intuition subscale reflecting favouring an intuitive approach to CSA investigations; and (4) The Anti Criminal Justice System subscale reflecting negative attitudes towards the legal system. Beliefs that were erroneous according to empirical research were analyzed separately. The results suggest that some psychologists hold extreme attitudes and many erroneous beliefs related to CSA. Some misconceptions are common. Female participants tended to have stronger attitudes than male participants. The more training in interviewing children the participants had had, the more erroneous beliefs and stronger attitudes they had. Experience did not affect attitudes and beliefs.     

Personality and intimate partner aggression in dating relationships: the role of the "Big Five"

Although personality is shown to predict negative relationship experiences, few researchers have used a structural model of personality to study the ways that personality contributes to intimate partner aggression (IPA). This study investigates the five-factor model of personality and its associations with both the use and receipt of psychological, physical, and sexual IPA in 179 men and 301 women. Each of the five factors of personality was associated with at least one type of IPA perpetration or victimization. The dimensions of neuroticism and agreeableness were the strongest predictors of IPA particularly for women. Results are discussed in terms of why personality should be considered as a predictor for both the use and receipt of IPA, why sex differences emerged, and future research that should be conducted.
