Asian American college women's body image: a pilot study

The purpose of this study was to examine the effects of values acculturation and the influence of media on Asian American college women's overall body image. A sample of 59 Asian American women from two large universities completed self-report surveys, which included questions regarding values acculturation, media internalization, and overall body satisfaction. Results showed that Asian American women who identified more strongly with traditional Asian values reported higher levels of body image dissatisfaction. Further, Asian American women who reported higher internalization of media portrayals of beauty ideals reported higher body image dissatisfaction. Research and clinical recommendations are made to enhance psychologists' understanding of Asian American women's body image and acculturation.     

Dynamic response-by-response models of matching behavior in rhesus monkeys

We studied the choice behavior of 2 monkeys in a discrete-trial task with reinforcement contingencies similar to those Herrnstein (1961) used when he described the matching law. In each session, the monkeys experienced blocks of discrete trials at different relative-reinforcer frequencies or magnitudes with unsignalled transitions between the blocks. Steady-state data following adjustment to each transition were well characterized by the generalized matching law; response ratios undermatched reinforcer frequency ratios but matched reinforcer magnitude ratios. We modelled response-by-response behavior with linear models that used past reinforcers as well as past choices to predict the monkeys' choices on each trial. We found that more recently obtained reinforcers more strongly influenced choice behavior. Perhaps surprisingly, we also found that the monkeys' actions were influenced by the pattern of their own past choices. It was necessary to incorporate both past reinforcers and past choices in order to accurately capture steady-state behavior as well as the fluctuations during block transitions and the response-by-response patterns of behavior. Our results suggest that simple reinforcement learning models must account for the effects of past choices to accurately characterize behavior in this task, and that models with these properties provide a conceptual tool for studying how both past reinforcers and past choices are integrated by the neural systems that generate behavior.     

Aggressive disposition,alcohol, and aggression

This study investigated the effect of aggressive disposition on intoxicated and non-intoxicated aggressive behavior. Prior aggressiveness was measured with a structured questionnaire. Based on a bipartite split of scores, 28 subjects were assigned to the high aggressor group, and 29 to the low aggressor group. Subjects in both disposition groups were then randomly assigned to either a drunk or sober condition, and participated in a competitive reaction time task involving the administering and receiving of electric shocks to/from a fictitious opponent under conditions of high and low provocation. Aggression was defined as shock level intensity delivered to the sham opponent. When highly provoked, sober high aggressors were significantly more aggressive than low aggressors, thus validating the measure of aggressive disposition. When intoxicated, highly provoked individuals in both the high and low aggressive disposition groups attained equal levels of aggression. It was low aggressors who responded to escalated provocation with a significant increase in aggression responding when intoxicated. These results lend support to the notion that a pharmacological effect of alcohol can increase aggressive behaviour. Aggr. Behav. 23:11–18, 1997. © 1997 Wiley-Liss, Inc.     

Correlates of suicidal behaviors among Asian American outpatient youths

Medical record abstraction was conducted at an ethnic-specific mental health outpatient clinic to identify correlates of suicidal behaviors in a sample of 285 Asian American youths. Some risk factors, such as parent-child conflict and age, which have been associated with suicidality in majority group youths, predicted suicidality in this sample, whereas other risk factors, such as gender, did not generalize to this sample. Acculturation interacted with the risk factor of parent-child conflict to predict suicidality. Less acculturated Asian youths were at proportionally greater risk for suicidality under conditions of high parent-child conflict than were their more acculturated counterparts. This finding underscores the importance of culture as a context for determining the relevance of stressors for potentiating psychopathology.     

A multi-perspective multi-domain model of self-concept: structure and sources of self-concept knowledge

A perspective-specific model which deals with the sources of self-concept knowledge as construed by two theories (symbolic interaction and social comparison) was combined with Shavelson's domain-specific model to form a two-facet model of self-concept. The structure of this two-facet model was tapped by a new self-concept instrument, the Multi-Perspective Multi-Domain Self-Concept Inventory (MMSI), which was constructed by crossing domain and perspective facets. Results of confirmatory factor analysis by grade level of the data from a large sample of primary two, four, and six students lent support to the multi-perspective multi-domain model. The MMSI facilitates the estimation of (a) the differential contribution of domain and perspective factors, and (b) the differential contribution of different sources of self-concept knowledge. It also serves as an exemplar of an interesting application of the multi-trait multi-method model in confirmatory factor analysis.     

Personal Spiritual Values and Quality of Life: Evidence from Chinese College Students

Values are guiding principles in our life. While some studies found spiritual values to be “healthier,” Sagiv and Schwartz (Eur J Soc Psychol 30:177–198, 2000) showed that people holding non-spiritual values were higher on affective well-being. We examined the predictive power of these two types of values with a longitudinal data set collected from Chinese students mainly in Hong Kong. Structural equation modeling revealed that spiritual values (as well as family income) positively predicted quality of life a year later. Non-spiritual, self-enhancement values, did not show any association. Results suggest that developing spiritual values may promote well-being through enabling individuals to find meaning and purpose in life.     

A depleted mind feels inefficacious: Ego‐depletion reduces self‐efficacy to exert further self‐control

Recent research has found that ego‐depletion undermines self‐control by motivating cognition that justifies conservation of mental resource. One potential cognitive mechanism is reduction of self‐efficacy. Specifically, we propose that ego‐depletion might demotivate self‐control by making people believe that they are inefficacious in exerting self‐control in subsequent tasks. Three experiments support the proposal. First, we demonstrated that (a) ego‐depletion can reduce self‐efficacy to exert further control (Experiments 1 to 3) and (b) the temporary reduction of self‐efficacy mediates the effect of depletion on self‐control performance (Experiment 2). Finally, we found that (c) these effects are only observed among participants who endorse a limited (versus non‐limited) theory of willpower and are, hence, more motivated to conserve mental resources (Experiment 3). Taken together, the present findings show that decrease in self‐efficacy to exert further self‐control is an important cognitive process that explains how ego‐depletion demotivates self‐control. This research also contributes to the recent discussion of the psychological processes underlying ego‐depletion.     

The Impact of Latino Caregiver Acculturation on Treatment Engagement in Children’s Community Mental Health Services

Ongoing treatment engagement is low in children’s community mental health. Although concerns are more pronounced for racial/ethnic minorities, findings have been mixed when comparing racial/ethnic minorities with Non-Hispanic Whites. Within-group variability, such as level of acculturation, may be a more proximal predictor of treatment engagement. The current study aimed to examine the effect of Latino caregivers’ acculturation on ongoing treatment engagement indicators, specifically session attendance, premature treatment termination, and treatment satisfaction. Participants were families of youth, ages 5–15, with a Latino primary caregiver (N = 93) receiving treatment for anxiety/trauma, depression, or disruptive behavior problems in community-based mental health agencies. Caregivers were classified into low and high acculturation groups using latent class analysis based on demographic indicators, such as nativity status and primary language spoken. Groups significantly differed in terms of caregivers’ nativity status, age at immigration, primary language spoken, language of study assessment completion, and language spoken in the home. Families of low acculturation caregivers no showed to significantly fewer planned treatment sessions than families of highly acculturated caregivers. Treatment satisfaction did not differ between groups. Low acculturation families also had lower odds of prematurely withdrawing from treatment. Results of this study highlight the importance of considering family characteristics such as acculturation when engaging families in treatment.
