RESUMO
Objective To examine the impact of psychosocial factors on physical activity,so as to provide guidance for the development of an effective physical activity intervention program for individuals with hypertension.Methods This study used a baseline data from an intervention study on regular physical activity among hypertensive individuals.A multi-stage,stratified random sampling was utilized and finally 12 communities from 6 urban districts were chosen.Questionnaires were administrated through face-to-face interviews.A total of 586 participants were recruited and finally 559 completed the interviews with the response rate as 95.4％.Descriptive statistics and Cronbach' sα coefficients were used to test the reliability.General Linear Model analysis was used to analyze the relationship between stages of physical activity and psychological factors.Results Psychosocial measures on physical activity demonstrated good reliability with Cronbach α coefficient from 0.7 to 0.9.The scores for each psychological measures increased by increasing the scores of stages of physical activity.General Linear Model analysis revealed self-efficacy (β=0.379) while enjoyment of physical activity (β =0.234) was significantly correlated with physical activity (P＜0.05).The behavioral processes and family support marginally increased the physically activity (β =0.069 for behavioral processes and β=0.163 for family support,P＜0.10).Conclusion Our findings were informative for the development of community-based intervention programs on physical activity among hypertensive individuals.It indicated that physical activity intervention programs should be psychosocial theory-based,especially increasing their self-confidence and enjoyment,as well as with family support,in order to adopt and maintain the physical activities.
RESUMO
Objective To understand the relationship of tendency on drug abuse and related influencing factors for middle school students.Methods A total of 603 students wcre assessed with self-made copying style scale,consciousness to resistance of smoking,drinking and resistance ability through a questionnaire.A relationship model was set up by structure equation modeling.Results Copying style and resistance ability had significantly direct influence on tendency of drug abuse(with standardized coefficients were 0.202 and 0.092 respectively).Consciousness to resistance of smoking and drinking had significantly indirect influence on tendency of drug abuse.The goodneSS of fit for the structural equation model was satisfactory,with GFI,AGFI,RMSEA as 0.981,0.972 and 0.014 respectively.Conclusion It Was meaningful to grasp some copying skills and resistance ability to lower the tendency of drug abuse in middle school students.
RESUMO
<p><b>OBJECTIVE</b>To investigate the social mental state of drug addicts in a compulsive drug abuse treatment center; evaluate the effectiveness of integrated program for the prevention of abuse relapse and improvement of drug addicts' psychological health.</p><p><b>METHODS</b>The study subjects were addicts from the Wuhan Compulsive Drug Abuse Treatment Center between October 2003 and June 2004, who satisfied the inclusion criteria. A non-randomized control-intervention study design was adopted. Volunteers willing to take part in intervention were put into the intervention group with their full awareness and willingness to prevent drug abuse relapse. The control group was composed of the addicts who were willing to prevent relapse and to be followed up after their discharge.</p><p><b>RESULTS</b>The effectiveness of the integrated intervention program in promoting addicts' psychological health: before the intervention, the scores of Self-Rating Anxiety Scale (SAS), the positive and negative dimensionalities of Simple Coping Style Questionnaire (SCSQ) and Chinese Perceived Stress Scales (CPSS) had no significant differences between the intervention group and the control group. After the intervention, except that the SCSQ's positive dimensionality in the intervention group was significantly higher than that in the control group, other indices in the intervention group were lower. Before and after the intervention, the psychological health level in both the groups was lower than that in the normal population; there were significant differences between addicts and normal subjects in regards with all of the indices above.</p><p><b>CONCLUSION</b>Drug abuse was associated closely with addicts' social mental factors. The integrated intervention program can alleviate anxiety and stress, reduce co-morbid mental disorders and effectively improve their coping style. In conclusion, the program can promote addicts' psychological health significantly.</p>
