Overview
Brief Summary
To develop a family-based intervention with components of engagement, family roles, affection, and competence and verify its effectiveness on drug abstinence and family functioning for drug-abusing adults in Hong Kong; To compare the difference between family-based intervention and routine care which mainly consists of individual counselling services for drug abusers.
Detailed Description
This is a quasi-experimental trial examining the effects of a proposed family-based intervention for drug abusers on motivating them to stay drug abstinence and improve family functioning, in which 40 drug abusers with focal families (including spouses and/or children) will be recruited for intervention group receiving both family-based intervention and routine care and 40 drug abusers without involving family will be recruited for comparison group receiving routine care. In the in-take, drug-abusing subjects will be given a brief introduction and invited to provide basic background information about themselves and families. After filling the informed consent, participants will be assigned to intervention group or comparison group according to whether their family will join sessions together. After drug abusers and families fill in the online questionnaire at the baseline (T0), the intervention group will receive family-based intervention and routine care in one month, while the comparison group will receive only routine care in one month. Both groups will be assessed at two time points after intervention period (T1 = 1-month after baseline; T2 = 2-month after baseline). As hypothesized, the intervention group will show a greater reduction in the primary outcomes of drug use and greater increase in the secondary outcomes of family functioning than the comparison group. A repeated-measures analysis of covariance will be conducted to assess the effects of family-based intervention.

Outcomes
Primary Outcomes
Changes from baseline measurements of drug abstinenceat at 1- and 2-months
Time Frame: Baseline, 1- and 2-months
Changes in scores on drug abstinence is assessed by Timeline Followback (TLFB) in which participants will report the specific date and time of using drugs in the past one month. A higher score suggests a longer time for drug abstinence.
Changes from baseline measurements of frequency of drug use at 1- and 2-months
Time Frame: Baseline, 1-, and 2-months
Changes in scores on frequency of drug use is measured by Frequency of Drug Use in Past Three Months by Beats Drug Fund. A higher score suggests a higher frequency of drug use.
Secondary Outcomes
- Changes from baseline measurement of marital affection at 1- and 2-months(Baseline, 1- and 2-months)
- Changes from baseline measurement of family functioning at 1- and 2-months(Baseline, 1- and 2-months)
- Changes from baseline measurement of family roles at 1- and 2-months(Baseline, 1- and 2-months)
- Changes from baseline measurement of parenting competency at 1- and 2-months(Baseline, 1- and 2-months)
- Changes from baseline measurement of mental health at 1- and 2-months(Baseline, 1- and 2-months)
