Clinical Trial Summary

This case series and feasibility trial evaluated a novel integrated cognitive behavioral treatment, which was adapted specifically for homeless individuals and developed to treat substance use and depressive symptoms simultaneously. The integrated cognitive behavioral treatment was delivered among four homeless individuals enrolled in the Treatment First program (a social services program where treatment is offered in conjunction with temporary transitional housing), who had access to stable and sober housing milieus.

Description:

All study participants were clients at the social welfare office for the homeless, a specialized unit within the social services in Stockholm, Sweden. The participants were referred to outpatient treatment at Pelarbacken, a specialized primary care center for homeless patients.

The integrated cognitive behavioral treatment was developed as part of a collaborate treatment program between the social welfare office for the homeless and Pelarbacken. Post treatment interviews and individual behavioral analyses of prior patients showed that the far most common reason for alcohol or drug use, was coping with negative affect (46% reported this reason). The integrated cognitive behavioral treatment was developed emanating from the following analysis (1) being homeless often implicates having lost contact with several important life areas, substance use might be the only reinforcing activity left; (2) common reactions are stress and depressive symptoms, and avoidance based strategies such as passivity, isolation, avoidance of social contact, or substance use; (3) when decreasing substance use, a transient approximate 3 month period of increased "depression-like" symptoms occurs, which might lead to lapses or relapses (this period is also called post-acute abstinence, or protracted abstinence). The ICBT (5-15 sessions) was developed to extend over this time period, with the overall aim of participants to (1) access a stable, sober housing milieu, and decrease substance use; (2) learn strategies to cope with negative affect; and (3) learn strategies to cope with life changes, increase activities such as work, social contact, exercise or leisure activities.

Measures were administered at pre treatment, weekly during treatment, after treatment, and at 3-, 6- and 12-month following treatment cessation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The TimeLine Follow Back	The TimeLine Follow Back, a retrospective calendar instrument to assess days and quantity of alcohol and drug use, was used as primary measure for substance use. The TimeLine Follow Back have been found to have good psychometric properties in a homeless population (Sacks et al., 2003). Number of units (alcohol or drug use) per week were reported as means per week, during baseline and treatment. The TimeLine Follow Back was not administered at follow up.	A retrospective 90-day TimeLine Follow Back interview at baseline, and a retrospective 7 days TimeLine Follow Back self-report measure assessed weekly during treatment sessions (up to 15 sessions/weeks).
Secondary	The Patient Health Questionnaire	The Patient Health Questionnaire is a 9-item self-report measure (score range 0-27) that assesses depression severity with the following cut-off categories: None-minimal (0-4), mild (5-9), moderate (10-14), moderately-severe (15-19), severe (20-27).	1 week
Secondary	The Generalized Anxiety Questionnaire	The Generalized Anxiety Questionnaire is a 7 item self- report measure (score range 0-21) to assess anxiety, with the following cut-off categories: Mild (5-9), moderate (10-14), severe (15-21).	2 weeks
Secondary	The Alcohol Use Disorders Identification Test	The Alcohol Use Disorders Identification Test is a 10 item self-report measure (score range 0-40) that assesses alcohol consumption. A cut-off of 8 and 6, indicates a hazardous and harmful pattern of alcohol consumption for men and women, respectively.	1 year
Secondary	The Drug Use Disorders Identification Test	The Drug Use Disorders Identification Test is a 11 item self-report measure (score range 0-44) to identify and assess non-alcohol drug use patterns. A cut-off score of 6 and 2 indicates problematic drug use for men and women, respectively; and a score of =25 indicates heavily dependence on drugs.	1 year
Secondary	Housing status	The degree of homelessness was assessed with the questions "When was the last time that you had a housing of your own?" and "Where did you sleep last night?", with response alternatives based upon the Swedish national definition of homelessness: "Outside"; "At a shelter"; "In a temporary (sober) residential institution", "In a reference-based training or trial apartment", or "In my own apartment (own lease)". In addition, information of the participants' housing status was collected from the registers of the social welfare office for the homeless at baseline and follow up.	1 day
Secondary	The Credibility/Expectancy Questionnaire	Treatment credibility and expectancy was measured with the Credibility/Expectancy Questionnaire (score ranges credibility 1-19, and expectancy 0-100%, respectively). Higher scores indicate higher treatment credibility/expectancy.	1 day
Secondary	The Client Satisfaction Questionnaire	Treatment satisfaction was measured with the Client Satisfaction Questionnaire (score range 8-32). Higher scores indicate higher treatment satisfaction.	1 day
Secondary	Adverse events	The participants reported adverse events using a self-report measure adapted for psychological treatment. The adverse events measure does not include a total score or a score range, instead each adverse event experienced during treatment is reported. For each adverse event reported participant also rated the discomfort caused by the event when it occurred, as well as residual discomfort (level of discomfort at the time of assessment). Each adverse event reported is rated between 0 ("did not affect me at all") and 3 ("affected me very negatively").	Through study completion, 1 year
