Identifying trajectories of adolescent smoking: an application of latent growth mixture modeling.

The goal of the current study was to identify discrete longitudinal patterns of change in adolescent smoking using latent growth mixture modeling. Five distinct longitudinal patterns were identified. A group of early rapid escalators was characterized by early escalation (at age 13) that rapidly increased to heavy smoking. A pattern characterized by occasional puffing up until age 15, at which time smoking escalated to moderate levels was also identified (late moderate escalators). Another group included adolescents who, after age 15, began to escalate slowly in their smoking to light (0.5 cigarettes per month) levels (late slow escalators). Finally, a group of stable light smokers (those who smoked 1-2 cigarettes per month) and a group of stable puffers (those who smoked only a few puffs per month) were also identified. The stable puffer group was the largest group and represented 25% of smokers.     

An emotional processing writing intervention and heart rate variability: the role of emotional approach

Expressing and understanding one's own emotional responses to negative events, particularly those that challenge the attainment of important life goals, is thought to confer physiological benefit. Individual preferences and/or abilities in approaching emotions might condition the efficacy of interventions designed to encourage written emotional processing (EP). This study examines the physiological impact (as indexed by heart rate variability (HRV)) of an emotional processing writing (EPW) task as well as the moderating influence of a dispositional preference for coping through emotional approach (EP and emotional expression (EE)), in response to a laboratory stress task designed to challenge an important life goal. Participants (n?=?98) were randomly assigned to either EPW or fact control writing (FCW) following the stress task. Regression analyses revealed a significant dispositional EP by condition interaction, such that high EP participants in the EPW condition demonstrated higher HRV after writing compared to low EP participants. No significant main effects of condition or EE coping were observed. These findings suggest that EPW interventions may be best suited for those with preference or ability to process emotions related to a stressor or might require adaptation for those who less often cope through emotional approach.     

Parental loss, trusting relationship with current caregivers, and psychosocial adjustment among children affected by AIDS in China

The objective of this study was to examine the relationship between parental loss, trusting relationship with current caregivers, and psychosocial adjustment among children affected by AIDS in China. In this study, cross-sectional data were collected from 755 AIDS orphans (296 double orphans and 459 single orphans), 466 vulnerable children living with HIV-infected parents, and 404 comparison children in China. The trusting relationship with current caregivers was measured with a 15-item scale (Cronbach's α?=?0.84) modified from the Trusting Relationship Questionnaire developed by Mustillo et al. in 2005 (Quality of relationships between youth and community service providers: Reliability and validity of the trusting relationship questionnaire. Journal of Child and Family Studies, 14, 577-590). The psychosocial measures include rule compliance/acting out, anxiety/withdrawal, peer social skills, school interest, depressive symptoms, loneliness, self-esteem, future expectation, hopefulness about future, and perceived control over the future. Group mean comparisons using analysis of variance suggested a significant association (p?相似文献   

Spatial knowledge of a real school environment acquired from virtual or physical models by able-bodied children and children with physical disabilities

In Experiment 1, 2 groups of able-bodied children were exposed to both a complex single-tier virtual environment (VE) and a physical model of a different environment. For 1 group, the VE accurately modeled a real school, and for the other group the physical model did so. In transfer testing in the real school, orientation accuracy was greater in the group exposed to the VE of the real school. In Experiment 2, children with physical disabilities explored the VE model of the real school and were tested as in the 1st experiment. Measures of orientation accuracy and map-placing were significantly better in this group than in the guessing adult control group. The results illustrate the potential for VEs as useful spatial training media.     

“My Life is Too Chaotic to Practice What I Preach”: Perceived Benefits and Challenges of Being an Academic Women in Family Therapy and Family Studies Programs

The purpose of this study was to explore the experience of female faculty in family therapy and family studies graduate programs. Specifically, we were interested in how female faculty members in these programs experienced their roles as academics, partners, and/or parents. We conducted a discovery-oriented study qualitative study of 62 female academics in family studies and family therapy disciplines to identify the greatest concerns and benefits experienced by women in a family-studies-oriented academic field. Using a content analysis, we found that women in family studies/family therapy academic programs experience both high rewards and high demands and struggle with choosing among competing values. Additionally, the participants perceived support from colleagues, professional institutions, and family members as crucial to a female academic’s ability to perform up to expectations. We also offer suggestions for further research.     

Adult ADHD: Associations with Personality and Other Psychopathology

The goals of this study were to explicate adult ADHD’s relations with personality at both the domain and facet levels and to examine its associations with other psychological symptoms. Community members (N?=?294) completed measures assessing ADHD inattentive and hyperactive/impulsive symptoms, five-factor model personality domains and facets, and other internalizing and externalizing symptoms. Inattentiveness showed strong negative relations with conscientiousness and extraversion and strong positive relations with neuroticism; in contrast, hyperactivity/impulsivity related negatively to agreeableness, positively to extraversion, and weakly to neuroticism. Whereas inattentiveness emerged as a positive predictor of internalizing psychopathology—and depression in particular—hyperactivity/impulsivity related weakly to internalizing but more strongly to externalizing psychopathology. Thus, inattentive and hyperactive/impulsive symptoms showed differential relations with personality—at both the domain and facet levels—and with other psychological symptoms. These results demonstrate the value in examining ADHD’s relations with personality facets and with a wide range of psychopathology within the same study.     

Predictors of psychological outcomes in a longitudinal study of Latina breast cancer survivors

Objective: This study sought to investigate the unique contributions of socio-ecological, cultural and cancer treatment-related factors in predicting depressive symptoms and cancer-specific distress among Latinas. Design: Participants were 140 English or Spanish-speaking Latinas (M_age = 50.6) with non-metastatic breast cancer who were assessed within two years of diagnosis (Time 1) and three months later (Time 2).

Main Measures: Hierarchical regression analyses identified predictors of depressive symptoms and cancer-specific distress at Time 1 and 2.

Results: Most women scored above the clinical cut-offs for depressive symptoms and cancer-specific distress. After adjusting for socio-ecological factors, greater Latino enculturation, measured by Latino ethnic identity, was significantly associated with greater cancer-specific distress at Time 1 (β = .20, p < .05). A significant interaction (p < .01) revealed that among women high on Latino identity, lower English language use was associated with more cancer-specific distress than higher English language use. After adjusting for socio-ecological factors, greater satisfaction with surgical treatment predicted improved depressive symptoms and cancer-specific distress across time (β_s range from ?.31 to ?.18, p_s < .01).

Conclusions: Findings elucidate the complex relationship between culture and psychological outcomes in the breast cancer context and suggest that treatment satisfaction might be an important intervention target for Latinas.     

Feedback interference and dissociations of classification: Evidence against the multiple-learning-systems hypothesis

Researchers have argued that different categorization problems are learned by separate and distinct cognitive systems. They propose that an explicit system is responsible for learning rule-based categories and that a separate implicit system learns information-integration categories. One source of supporting evidence involves experiments in which observers perform a concurrent memory-scanning task that interferes with the processing of feedback. Researchers have reported a dissociation in which this manipulation impairs learning of a rule-based category but not an information-integration category. In the present research, we test the hypothesis that the dissociation was the result of lowered perceptual discriminability in the rule-based structure in comparison with the information-integration one. We demonstrate an example of an alternate rule-based category with easy-to-discriminate stimuli in which performance is unaffected by the interfering memory-scanning task. Furthermore, we demonstrate that learning of an information-integration category with low perceptual discriminability is impaired by the memory-scanning task. These demonstrations of the reverse dissociation challenge the interpretation that rule-based and information-integration category structures are learned by separate cognitive systems.     

Does self-affirmation, cognitive processing, or discovery of meaning explain cancer-related health benefits of expressive writing?

Although expressive writing has positive effects on health, little is known about the underlying psychological mechanisms for these effects. The present study assessed self-affirmation, cognitive processing, and discovery of meaning as potential mediators of the effects of expressive writing on physical health in early-stage breast cancer survivors. A content analysis of the essays showed that self-affirmation writing was associated with fewer physical symptoms at a 3-month follow-up assessment, with self-affirmation writing fully mediating the effects of the emotional expression and benefit-finding writing conditions on reduced physical symptoms. Cognitive processing and discovery of meaning writing were not associated with any physical health outcomes. Consistent with evidence showing that self-affirmation plays an important role in buffering stress, the present study provides the first evidence for self-affirmation as a viable mechanism underlying the health benefits of expressive writing.     

Individual and dyadic associations among relational self‐expansion potential,affect, and perceived health

A growing body of literature suggests that specific markers of relationship quality are meaningfully linked to health outcomes. We tested whether relational self‐expansion potential might be one of these markers in cross‐sectional samples of individuals and romantic couples. Study 1 found that greater self‐expansion potential was linked to better perceived physical health via both higher positive affect (PA) and lower negative affect (NA). Study 2 replicated these findings for PA (but not NA) and revealed both actor and partner effects of self‐expansion potential. Results remained robust when statistically accounting for gender, age, body mass index, agreeableness, neuroticism, and perceived partner responsiveness. These findings identify a new relationship‐level “active ingredient” associated with health and have implications for future physical health studies.
