Risky Sexual Behaviors and Condom Use Barriers in Iranian Women with Substance Use Disorders.

Scant information exists on Iranian women's protective behaviors mainly constant condom use. Inconsistent condom use seems prevalent among women with substance use problems. We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian women with substance use disorders (SUDs). In our cross-sectional study, we recruited 300 women who sought treatments for their SUDs from the active outpatient drug free (ODF) and Methadone Maintenance Therapy (MMT) centers in Tehran, Iran during 2017-2021. We used three batteries including demographic questionnaire, the Risky Sexual Behavior Questionnaire (RSBQ); and the Condom Barriers Scale (CBS). The statistical software R, analysis of variance post hoc and multivariate analysis of variance (MANOVA) logistic regression tests were used in data analysis. The majority reported at least one lifetime experience of RSBs. Our results show that only 22% of the participants 'always' use condom in their sexual encounters. The lowest and highest subscale scores of the CBS were related to Sexual Experience (SE) (2.47 ± 0.86) and access/availability structure (3.52 ± 0.7), respectively. RSBs had negative significant association with Partner Barrier (PB) subscale scores (OR = 0.4; 95% CI: 0.22 to 0.73) and effect on SE subscale scores (OR= 0.54; 95% CI: 0.31 to 0.94). RSBs was prevalent among our study population. RSBs and condom use barriers are significantly interwoven. The condom use barriers were highly associated with the types of sexual encounters such as group sex or casual sexual relations than specific mean of sexual performance (i.e. anal sex). Gender-specific RSBs, STIs/HIV/AIDS prevention program is recommended for women with SUDs.

Gender differences in sexual risk behaviors among population with substance use disorders, Iran

ABSTRACT Objective We examined gender differences in Sexual Risk Behaviors (SRBs) in Iranian individuals with Substance Use Disorders (SUDs). Methods A cross-sectional study conducted from late 2018 to the end of 2019 in Tehran province, Iran. Six outpatient drug-free (ODF) and methadone maintenance treatment program (MMTP) centers were selected. A total of 600 eligible participants (300 men; 300 women) were included in the study. Participants were investigated by trained interviewers using a questionnaire to collect information on SRBs. Data were analyzed using SPSS software version 24. Results Nearly 75% of participants (64% men and 84.3% women) reported at least one lifetime experience of SRBs. Men were 62% less likely than women to have SRBs. Also, 34.7% women and 3% men had reported sexual violence. Twenty-eight percent of women and 22% of men had a history of group sex. Sixty-nine women (23%) and 20 men (6.7%) reported having had sex with intravenous drug use (IDU) partner. During the past year, the majority of participants never consistently used condoms (83%) in their sexual encounters. Conclusions Iranian women with SUDs are more likely to be involved in SRBs than their men counterparts. The differences highlighted in this study should inform treatment centers to include “safer sex” interventions in their treatment programs.

Sexual Risk Behaviors and Condom Use Barriers in Iranian Men with Substance Use Disorders.

We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian men with substance use disorders (SUDs). Of the total 1800 outpatient drug free (ODF) and methadone maintenance treatment program (MMTP) active centers in Tehran, Iran, six were selected to participate in the current study. Data were collected (n = 300 men) using three questionnaires including a demographic questionnaire, the Risky Sexual Behavior Questionnaire (RSBQ), and the Condom Barriers Scale (CBS). The statistical software R, analysis of variance post hoc and multivariate analysis of variance (MANOVA) logistic regression tests were used in data analysis. The majority, (n = 194, 64.7%) reported at least one lifetime episode of RSBs. Compared to married participants (23.1%), 88.5% of single and 87.0% of divorced men had a history of RSB. Generally, the lowest and highest subscale scores of the CBS were related to sexual experience (2.60 ± 0.71) and access/availability structure (3.77 ± 0.54), respectively. The results of MANOVA analysis showed that there was a statistically significant difference between the CSB subscales based on the participants' education and marital status (P < 0.001). Only the partner barrier subscale had a significant negative relationship (P = 0.003) with RSB. Sexual dynamic of Iranian men with SUDs is different. Barriers to condom use seem to be socio-culturally determined. Culturally acceptable strategies need to be utilized in Iranian clinical settings reaching beyond simply condom accessibility for this at risk population.

Treatment program operations and costs

This study investigates how average costs for an episode of care in outpatient drug-free (ODF) treatment relate to clinical intensity (length of stay and weekly counseling hours) and program structure (e.g., size, staffing), controlling for prices paid and selected clientele measures. Based on cost assessments from a naturalistic sample of 67 programs located across the United States (using the Treatment Cost Analysis Tool), robust regression techniques showed that programs having 10% longer treatment stays had episode costs 7% higher; those having 10% more weekly counseling hours per client had 4% higher episode costs. Other important factors included wages, amount of counselors' time conducting sessions, and serving more clients referred from the criminal justice system. The study provides valuable information on treatment program features that relate to costs. Most importantly, cost differences associated with longer stays or more intensive counseling protocols appear modest and may be justified by improved client outcomes.

Physical Pain and Associated Clinical Characteristics in Treatment‐Seeking Patients in Four Substance Use Disorder Treatment Modalities

Physical pain among persons seeking treatment for substance use disorders (SUD) and characteristics associated with pain were examined in a secondary analysis of data from the Drug Abuse Treatment Outcome Study (DATOS), a multi-site treatment outcome study. Patients (N = 7,876) in four treatment modalities - long-term residential (LTR), short-term inpatient (STI), outpatient methadone treatment (OMT), and outpatient drug-free (ODF) - reported severity of physical pain experienced during the preceding 12 months. Moderate to severe physical pain was reported by 21.2% of LTR patients, 26.8% of STI patients, 33.6% of OMT patients, and 17.6% of ODF patients. Individuals with and without physical pain were compared across treatment modalities. Patients with pain were more likely to report weekly heroin use [aOR = 1.73 (1.44-2.08)], weekly narcotics use [aOR = 1.43 (1.18-1.74)] and greater depressive symptoms [aOR = 1.30 (1.21-1.38)]. These findings support the presence of a sizable proportion of SUD patients with pain who may benefit from pain assessment as part of their SUD treatment.

Overview of 5-year followup outcomes in the drug abuse treatment outcome studies (DATOS)

Followup results from the Drug Abuse Treatment Outcome Studies (DATOS) 1-year and 5-year followups were used to describe the long-term outcomes of drug treatment and to further clarify the relationship between treatment duration and post-treatment outcomes in four treatment modalities: outpatient methadone, long-term residential (LTR), outpatient drug free (ODF), and short-term inpatient. Methods replicating those used in earlier analyses of the DATOS 1-year followup of 2,966 patients admitted to treatment in 1991–1993 and those of the Treatment Outcome Prospective Study patients admitted in 1979–1981 were employed. DATOS is a non-experimental longitudinal study conducted within the natural settings of 96 treatment programs in the U.S.A. The study followed patients during and after treatment at specified periods of time. Prevalence of drug use and behaviors were evaluated for the year prior to treatment; and the post-treatment time frames defined by the 1- and 5-year followups. In addition, the multivariate analytic technique of generalized estimating equations was used to examine the relationship of treatment duration and outcomes across both followups while also controlling for patient characteristics and pretreatment levels of behaviors. The 5-year stratified followup sample included 1,393 of the same individuals in the 1-year followup sample. Analyses were restricted to patients participating in both followups. Reductions in prevalence of cocaine use in the year after treatment (compared to the preadmission year) by patients were associated with longer treatment durations (particularly 6 months or more in LTR and ODF). In addition, reductions in illegal activity and increases in full-time employment were related to treatment stays of 6 months or longer for patients in LTR. The DATOS results from the 1-year and 5-year post-treatment followup combined suggest the stability of outcomes of substance abuse treatment. While results are generally consistent with the full 1-year followup, reduced sample size and bias of the sample toward patients with longer treatment retention may have attenuated the findings.

Prospective Risk Factors and Treatment Outcomes among Adolescents in DATOS-A

The relationships between risk factors and outcomes in adolescents participating in the Drug Abuse Treatment Outcome Studies for Adolescents (DATOS-A) were examined. The study included 292 admissions to nine outpatient drug-free (ODF) and 418 admissions to eight residential (RES) programs. Assessments were administered at intake into treatment and 12 months following discharge. For ODF participants, (a) severity of drug use predicted less retention in treatment, and (b) family drug involvement predicted more alcohol use after treatment. For RES participants, (a) family drug involvement and criminal involvement predicted less treatment retention, and (b) conduct disorder predicted more marijuana use at follow-up. The findings underscore the need for intervention strategies that address the intrapsychic and interpersonal functioning of drug-abusing adolescents to improve their behavioral outcomes.

Transportation and retention in outpatient drug abuse treatment programs.

To determine whether certain types of transportation assistance improve outpatient treatment retention beyond thresholds shown to have therapeutic benefits, we analyzed data from 1,144 clients in 22 outpatient methadone maintenance (OMM) programs and 2,031 clients in 22 outpatient drug-free (ODF) programs in the Drug Abuse Treatment Outcomes Study (DATOS), a national, 12-month, longitudinal study of drug abuse treatment programs. Directors' surveys provided information about provision of car, van, or contracted transportation services or individual vouchers/payment for public transportation. Chart-abstracted treatment retention was dichotomized at 365 days for OMM and 90 days for ODF. Separate multivariate hierarchical linear models revealed that provision of car, van, or contracted transportation services improved treatment retention beyond these thresholds for both OMM and ODF, but individual vouchers or payment for public transportation did not. Future research should validate whether car, van, or contracted transportation services improve retention and other treatment outcomes in outpatient drug abuse treatment.

Retention and patient engagement models for different treatment modalities in DATOS

A model to explain treatment retention in terms of process components — therapeutic involvement and session attributes for the 1st month — and patient background factors were tested in long-term residential (LTR), outpatient drug free (ODF), and outpatient methadone (OMT) treatments. The data was collected in the national Drug Abuse Treatment Outcome Studies (DATOS), and included 1362 patients in LTR, 866 in ODF, and 981 in OMT programs. Structural equation models showed there were positive reciprocal effects between therapeutic involvement and session attributes in all three modalities, and these variables had direct positive effects on treatment retention. Motivation at intake was a strong determinant of therapeutic involvement. Other patient background factors were significantly related to retention, including pretreatment depression, alcohol dependence, legal pressure, and frequency of cocaine use.

Patient histories, retention, and outcome models for younger and older adults in DATOS

Structural equation modeling with multiple groups was used to examine relationships among pretreatment patient characteristics, treatment retention, and treatment outcomes among younger and older adults in the Drug Abuse Treatment Outcome Studies. Separate models were tested for 551 patients treated in long-term residential (LTR) programs and 571 patients treated in outpatient drug-free (ODF) programs. There was a stronger positive relationship between treatment retention and abstinence at follow-up for younger adults in both treatment modalities. Prior treatment history had a negative effect on self-efficacy to resist drug use for older adults in LTR. Negative reference group influence was reduced for all groups following treatment, however, it was more strongly related to abstinence for younger adults in LTR and for older adults in ODF. Clinical implications of age-related differences in these relationships are discussed.

Costs and benefits of treatment for cocaine addiction in DATOS

Our objective was to examine the cost of long-term residential (LTR) and outpatient drug-free (ODF) treatments for cocaine-dependent patients participating in the Drug Abuse Treatment Outcome Studies (DATOS), calculate the tangible cost of crime to society, and determine treatment benefits. Subjects were 502 cocaine-dependent patients selected from a national and naturalistic nonexperimental evaluation of community-based treatment. Financial data were available for programs from 10 US cities where the subjects received treatment between 1991 and 1993. Treatment costs were estimated from the 1992 National Drug Abuse Treatment Unit Survey (NDATUS), and tangible costs of crime were estimated from reports of illegal acts committed before, during, and after treatment. Sensitivity analyses examined results for three methods of estimating the costs of crime and cost-benefit ratios. Results showed that cocaine-dependent patients treated in both LTR and ODF programs had reductions in costs of crime from before to after treatment. LTR patients had the highest levels and costs of crime before treatment, had the greatest amount of crime cost reductions in the year after treatment, and yielded the greatest net benefits. Cost-benefit ratios for both treatment modalities provided evidence of significant returns on treatment investments for cocaine addiction.

Effects of readiness for drug abuse treatment on client retention and assessment of process.

This study examined client motivation as a predictor of retention and therapeutic engagement across the major types of treatment settings represented in the third national drug abuse treatment outcome study (DATOS) conducted in the United States. Sequential admissions during 1991-93 to 37 programs provided representative samples of community-based treatment populations. Based on this naturalistic non-experimental evaluation design, hierarchical linear model (HLM) analysis for nested data was used to control for systematic variations in retention rates and client attributes among programs within modalities. The data were collected from long-term residential (LTR), outpatient methadone (OMT) and outpatient drug-free (ODF) programs located in 11 large cities. A total of 2265 clients in 18 LTR, 981 clients in 13 OMT and 1791 clients in 16 ODF programs were studied. Pre-treatment variables included problem recognition and treatment readiness (two stages of motivation), socio-demographic indicators, drug use history and dependence, criminality, co-morbid psychiatric diagnosis and previous treatment. Retention and engagement (based on ratings of client and counselor relationships) served as outcome criteria. Pre-treatment motivation was related to retention in all three modalities, and the treatment readiness scale was the strongest predictor in LTR and OMT. Higher treatment readiness also was significantly related to early therapeutic engagement in each modality. Indicators of intrinsic motivation--especially readiness for treatment--were not only significant predictors of engagement and retention, but were more important than socio-demographic, drug use and other background variables. Improved assessments and planning of interventions that focus on stages of readiness for change and recovery should help improve treatment systems.

Effects of readiness for drug abuse treatment on client retention and assessment of process

Aims. This study examined client motivation as a predictor of retention and therapeutic engagement across the major types of treatment settings represented in the third national drug abuse treatment outcome study (DATOS) conducted in the United States. Design. Sequential admissions during 1991‐93 to 37 programs provided representative samples of community‐based treatment populations. Based on this naturalistic non‐experimental evaluation design, hierarchical linear model (HLM) analysis for nested data was used to control for systematic variations in retention rates and client attributes among programs within modalities. Setting. The data were collected from long‐term residential (LTR), outpatient methadone (OMT) and outpatient drug‐free (ODF) programs located in 11 large cities. Participants. A total of 2265 clients in 18 LTR, 981 clients in 13 OMT and 1791 clients in 16 ODF programs were studied. Measurements. Pre‐treatment variables included problem recognition and treatment readiness (two stages of motivation), socio‐demographic indicators, drug use history and dependence, criminality, co‐morbid psychiatric diagnosis and previous treatment. Retention and engagement (based on ratings of client and counselor relationships) served as outcome criteria. Findings. Pre‐treatment motivation was related to retention in all three modalities, and the treatment readiness scale was the strongest predictor in LTR and OMT. Higher treatment readiness also was significantly related to early therapeutic engagement in each modality. Conclusions. Indicators of intrinsic motivation‐especially readiness for treatment‐were not only significant predictors of engagement and retention, but were more important than socio‐demographic, drug use and other background variables. Improved assessments and planning of interventions that focus on stages of readiness for change and recovery should help improve treatment systems.

Effects of drug misuse treatment on symptoms of depression and suicide.

In this longitudinal study of 9,904 clients who were treated at methadone, outpatient drug-free (OPDF), and residential treatment facilities, at intake more than half of all clients reported symptoms of depression or suicide. Females and multiple nonnarcotics users were at highest risk for suicide attempts. Despite a dramatic drop in the level of symptomatology by 4 weeks in treatment, many clients remained suicidal throughout the study period. Suicidal tendencies at both intake and 4 weeks were strongly related to suicidal tendencies at 12 months post-treatment; even more strongly related was the return to weekly or more frequent use of narcotics or nonnarcotics for residential and OPDF clients.

Family therapy vs. parent groups: Effects on adolescent drug abusers

Abstract The families of adolescent drug abuse clients who were admitted to six outpatient drug-free (OPDF) treatment programs were randomly assigned to either a family therapy method or a parent group method. It was later found that in 93% of the family therapy families, one or both parents participated (N=85); but that in only 67% of the families assigned to a parent group did one or both parents participate (N=50). This is considered to be an important practical advantage for family therapy. At follow-up evaluation 15 months later (after a 6-month course of treatment and a 9-month follow-up period), the clients and their mothers in both groups reported significant improvement on numerous outcome criteria, including reduction in substance use. There was no significant difference between the two groups in degree of improvement.
