An experience-sampling study of depressive symptoms and their social context.
(J Nerv Ment Dis, 2011-06) Brown, Leslie H; Strauman, Timothy; Barrantes-Vidal, Neus; Silvia, Paul J; Kwapil, Thomas R
Both clinical and subclinical depression are associated with social impairment; however, few studies have examined the impact of social contact in the daily lives of people with depressive symptoms. The current study used the experience-sampling methodology to examine associations between depressive symptoms, social contact, and daily life impairment in 197 young adults. Depressive symptoms were associated with increased isolation, negative affect, anhedonia, and physical symptoms, decreased positive affect, and social and cognitive impairment in daily life. For people with more depressive symptoms, being with social partners who were perceived as close was associated with greater decreases in negative affect, as well as increases in positive affect. Ironically, participants with depressive symptoms reported spending less time with people whom they perceived as close, minimizing the protective effects of socializing. These results suggest that people experiencing depressive symptoms may be especially sensitive to the nature of social interactions.

Tobacco smoking and other suspected antecedents of nonmedical psychostimulant use in the United States, 1995.
(Substance use & misuse, 1999-07) Wu, LT; Anthony, JC
This study investigates the extent to which tobacco smoking is associated with the nonmedical use of psychostimulants and the temporal order of the age of first use for tobacco and psychostimulants within a nationally representative sample of United States household residents. At the same time, alcohol use and other suspected determinants of psychostimulant use are investigated and held constant, using multiple regression models. Data were taken from public use files of the 1995 National Household Survey on Drug Abuse. Conditional logistic regression analyses were performed to derive estimated relative odds of using stimulants for tobacco smokers versus nonsmokers, holding constant other potentially distorting influences. This study provides recent evidence on tobacco smoking as one of the potentially malleable risk factors for the nonmedical use of stimulant drugs.

Use of alcohol treatment and mental health services among adolescents with alcohol use disorders.
(Psychiatric services (Washington, D.C.), 2006-01) Wu, Li-Tzy; Ringwalt, Chris L
OBJECTIVE:This study examined the use of and perceived need for alcohol treatment services among adolescents (aged 12 to 17 years) who received mental health services in the previous year compared with same-aged adolescents who did not receive such services. METHODS:Study data were drawn from the 2000 and 2001 National Household Surveys on Drug Abuse. The authors conducted logistic regression analyses to identify the characteristics associated with the receipt of and perceived need for alcohol services among adolescents with alcohol use disorders. RESULTS:Adolescents who received mental health services were much more likely than those who did not to meet criteria for alcohol use disorders in the previous year (10 percent compared with 4 percent). Among adolescents with alcohol use disorders, 15 percent of those who received mental health services used any alcohol services, compared with only 6 percent of those who did not receive mental health services. Of adolescents with alcohol use disorders who did not receive any alcohol services, only 3 percent reported a need for alcohol treatment. Among adolescents with alcohol use disorders who received mental health services, Hispanics were significantly less likely than whites to receive any alcohol services. CONCLUSIONS:These findings from a nationally representative sample of adolescents reveal a largely unrecognized and underserved population at risk. Factors related to the underutilization of alcohol services by adolescents with alcohol use disorders deserve greater research attention.
