Depression

Abstract— The theory of clinical depression presented here integrates etiological factors, changes in specific structural and cellular substrates, ensuing symptomatology, and treatment and prevention. According to this theory, important etiological factors, such as stress, can suppress the production of new neurons in the adult human brain, thereby precipitating or maintaining a depressive episode. Most current treatments for depression are known to elevate brain serotonin neurotransmission, and such increases in serotonin have been shown to significantly augment the ongoing rate of neurogenesis, providing the neural substrate for new cognitions to be formed, and thereby facilitating recovery from the depressive episode. This theory also points to treatments that augment neurogenesis as new therapeutic opportunities.     

‘And what about residential…?’ Re‐conceptualizing residential treatment as a stop‐gap service for youth with emotional and behavioral disorders

The need for residential services for youth with the most intractable emotional and behavioral problems continues to exist despite advances made in developing community‐based systems of care. Residential treatment centers (RTCs), considered one of the most restrictive service settings, have changed little over the years and have not fared well in outcome evaluations. Despite these factors, admissions to RTCs continue to increase. In an attempt to contemporize and bring the RTC more in line with current practice, a stop‐gap model of service delivery is recommended. The stop‐gap model, incorporating evidence‐based practices, is intended to have an immediate and positive impact on the barrier behaviors that keep youths in the most restrictive environments. The twofold goal of the stop‐gap model is to interrupt the youth's downward spiral imposed by increasingly disruptive behavior and, simultaneously, to prepare the post‐discharge environment for the youth's timely reintegration. Strategies for evaluating the effectiveness of the stop‐gap model are recommended. Copyright © 2004 John Wiley & Sons, Ltd.     

Cultural and demographic correlates of self‐reported guardedness among East Asian immigrants in the US

The study examined guarded self‐disclosure or reticence to reveal personal information about oneself to others among East Asian immigrants in the United States, in terms of cultural (ethnic identity, self‐construal, and acculturation) and demographic (gender, age, number of years in the US, and English fluency) variables. Norms regarding appropriate amount, content, and type of self‐disclosure differ noticeably between Asian and American cultures. In general, Asians have been found to be more guarded in their self‐disclosure than their American counterparts. Such differences may hinder the formation of relationships between Asian immigrants and Americans. Thus, it is important for psychologists to examine culture‐specific and non‐culture‐specific correlates of guarded self‐disclosure among Asian immigrants in the United States. However, to date, there has been a dearth of studies examining this topic. This paucity of research is somewhat surprising given the large number of Asian immigrants in the United States. The participants included 170 East Asian immigrants (88 males, 82 females) who were administered a battery of psychometrically established measures. While guarded self‐disclosure did not vary by ethnic group (i.e., Chinese, Japanese, and Korean), it was associated with cultural and demographic variables. East Asian immigrants who exhibited guarded self‐disclosure were more likely to report elevated ethnic pride, interdependent self‐construal, separation, and marginalization, and were less likely to report elevated interpersonal distance, independent self‐construal, and integration. Men reported significantly higher guarded self‐disclosure than women. Overall, this study highlights the importance of assessing both culture‐specific and nonspecific factors in guarded self‐disclosure among East Asian immigrants. The findings emphasize the importance of considering more generic types of self‐disclosure in addition to disclosure of very private and/or distressing information. Awareness of the cultural correlates of guarded self‐disclosure may help counsellors target their outreach programmes for individuals of East Asian heritage.     

What we want to do versus what we think we should do: an empirical investigation of intrapersonal conflict

People often feel torn between what they want to do and what they believe they should do. As a result, they experience intrapersonal conflict. For example, people know that they should avoid credit card debt, but they want to splurge on just one more purchase. Following Loewenstein's ( 1996 ) temporal perspective to understanding internal conflict and inconsistency, we offer three studies that empirically demonstrate (1) a distinction between the want self and the should self, (2) that behavior is more closely linked to the want self, (3) that the want self is the self that is temporally inconsistent, and (4) that adopting a want versus should perspective can have a significant impact on actual behavior.

Predicting persistence or withdrawal in female handballers with social exchange theory

Two complementary studies were conducted to explain the dropout phenomenon with French female handball players, utilizing the tenets of social exchange theory (Thibaut & Kelley, 1959; Rusbult, 1980). In the first study, the aim was to more fully explore the sources of enjoyment by emphasizing the key variables in the costs/benefits analysis. We postulate that the costs/benefits analysis consists in each athlete estimating the probability of reaching the most desired consequences for him or her (e.g., learn and improve skill, affiliation with others, be better than the others). The subjects were 488 French women aged from 15–19 years. Structural equation modeling (SEM) revealed that enjoyment in handball was predicted by a latent variable (named perceived benefits) subjacent to perceptions of competence, autonomy, relatedness, progress, coach's support, and time of play. In the second study, we tested a sport commitment model based on the social exchange postulates, using SEM analyses and a prospective design over 8 months. In view of the results of study 1, we replaced the construct of enjoyment with perceived benefit. This analysis provides a more comprehensive understanding of the enjoyment construct and is more consistent with the notion of cost and benefits outlined in social exchange theory. Participants were 253 French handball players between the ages of 14 and 16 years. A first set of analyses, focused on the differences, showed that dropout players perceived themselves as significantly less competent, less autonomous, less related to their team, lower in progress and less supported by their coach than persistent players. The second set of analyses with SEM revealed that the commitment level was positively associated with perceived benefits and negatively with social constraints and alternatives opportunities. Finally, a lack of commitment led to dropping out of the sport 8‐months later.     

Reward Influence on the Heart: Cardiovascular Response as a Function of Incentive Value at Five Levels of Task Demand

This study examined cardiovascular effects of incentive value in men and women confronted with cognitive challenges that were more and less difficult to meet. Participants performed computer memory tasks varying in difficulty from low to high, with instructions that they could earn chances toward a $100 prize or $10 prize by attaining a 90% success rate. Analysis of cardiovascular responses assessed during work revealed an interaction between difficulty and incentive value for heart rate. Participants' heart rate responses were proportional to task difficulty and unaffected by incentive value in all conditions except for the most difficult one. Where difficulty was greatest, $100 participants showed relatively high heart rate responsiveness, whereas $10 participants showed low heart rate responsiveness. This heart rate finding corroborates and extends cardiovascular results from previous experiments, and lends further support to the view that cardiovascular responses will be proportional to incentive value only under some task conditions.     

Apples and Oranges Make a Nice Start for a Fruit Salad: A Response to Culbreth and Borders (1999)

These comments represent a response to J. R. Culbreth and L. D. Borders (1999) and suggest consideration of other factors when addressing the impact of clinical supervision in the addictions field. This article supports formal graduate academic preparation for substance abuse counselors and clinical supervisors and challenges the use of satisfaction surveys in measuring appropriateness of clinical supervision.     

The Effect of a Brief Mindfulness Training on Distress Tolerance and Stress Reactivity

Poor distress tolerance (DT) is considered an underlying facet of anxiety, depression, and a number of other psychological disorders. Mindfulness may help to increase DT by fostering an attitude of acceptance or nonjudgment toward distressing experiences. Accordingly, the present study examined the effects of a brief mindfulness training on tolerance of different types of distress, and tested whether trait mindfulness moderates the effect of such training. Undergraduates (n = 107) naïve to mindfulness completed a measure of trait mindfulness and underwent a series of stress tasks (cold pressor, hyperventilation challenge, neutralization task) before and after completing a 15-minute mindfulness training or a no-instruction control in which participants listened to relaxing music. Participants in the mindfulness condition demonstrated greater task persistence on the hyperventilation task compared to the control group, as well as a decreased urge to neutralize the effects of writing an upsetting sentence. No effect on distress ratings during the tasks were found. Overall trait mindfulness did not significantly moderate task persistence, but those with lower scores on the act with awareness facet of mindfulness demonstrated greater relative benefit of mindfulness training on the hyperventilation challenge. Mediation analyses revealed significant indirect effects of mindfulness training on cold pressor task persistence and urges to neutralize through the use of the nonjudge and nonreact facets of mindfulness. These results suggest that a brief mindfulness training can increase DT without affecting the subjective experience of distress.     

Teaching pronouns to individuals with autism

It is well documented that individuals with autism often have significant difficulty with learning to use pronouns appropriately. It does not appear, however, that published studies have systematically investigated teaching procedures for these skills. This study evaluated the effectiveness of a teaching procedure to increase correct pronoun usage as a listener and speaker across four different pronoun pairs (i.e., mine/yours, I/you, me/you, and my/your) using a multiple‐probe design (across pronoun pairs). One participant with autism was taught to discriminate between mine/yours, I/you, me/you, and my/your as both a listener and a speaker. Generalization of the participant's behavior was obtained across novel instructors, places, and stimuli.
