BackgroundIntegrated treatment programs (those that include on-site pregnancy-, parenting-, or child-related services with addiction services) were developed to break the intergenerational cycle of addiction, dysfunctional parenting, and poor outcomes for mothers and children, yet there has been no systematic review of studies of parenting outcomes.ObjectivesAs part of larger systematic review to examine the effectiveness of integrated programs for mothers with substance abuse issues, we performed a systematic review of studies published from 1990 to 2011 with data on parenting outcomes.MethodsLiterature search strategies included online bibliographic database searches, checking printed sources, and requests to researchers. Studies were included if all participants were mothers with substance abuse problems at baseline, the treatment program included at least one specific substance use treatment and at least one parenting or child service, and there were quantitative data on parenting outcomes. We summarized data on parenting skills and capacity outcomes.ResultsThere were 24 cohort studies, 3 quasi-experimental studies, and 4 randomized trials. In the three randomized trials comparing integrated programs to addiction treatment-as-usual (N = 419), most improvements in parenting skills favored integrated programs and most effect sizes indicated that this advantage was small, d s = -0.02 to 0.94. Results for child protection services involvement did not differ by group. In the three studies that examined factors associated with treatment effects, parenting improvements were associated with attachment-based parenting interventions, children residing in the treatment facility, and improvements in maternal mental health.ConclusionsThis is the first systematic review of studies evaluating the effectiveness of integrated programs on parenting. The limited available evidence supports integrated programs, as findings suggest that they are associated with improvements in parenting skills. However, more research is required comparing integrated programs to addiction treatment-as-usual. This review highlights the need for improved methodology, study quality, and reporting to improve our understanding of how best to meet the parenting needs of women with substance abuse issues.

Closing the Research-Practice Gap: Factors Affecting Adoption and Implementation of a Children's Mental Health Program

Joanna Henderson; Sherri MacKay; Michele Peterson-Badali

Despite the availability of effective interventions, they are not widely used in community mental health centers. This study examined the adoption and implementation of The Arson Prevention Program for Children (TAPP-C), a program for juvenile firesetters developed at a teaching hospital and disseminated to community settings. Questionnaire data from mental health professionals were used to evaluate the roles of adopter, innovation, and dissemination characteristics in TAPP-C adoption and implementation. Results indicate that different factors are important at different diffusion stages. Moreover, they suggest that innovation characteristics may be particularly important to adoption, whereas adopter and dissemination characteristics may be more influential in implementation.

BACKGROUND Integrated treatment programs (those that include on-site pregnancy-, parenting-, or child-related services with addiction services) were developed to break the intergenerational cycle of addiction, potential child maltreatment, and poor outcomes for children. OBJECTIVES To examine the impact and effects of integrated programs for women with substance abuse issues and their children, we performed a systematic review of studies published from 1990 to 2011. METHODS Literature search strategies included online bibliographic database searches, checking printed sources, and requests to researchers. Studies were included if all participants were mothers with substance abuse problems at baseline; the treatment program included at least 1 specific substance use treatment and at least 1 parenting or child treatment service; the study design was randomized, quasi-experimental, or cohort; and there were quantitative data on child outcomes. We summarized data on child development, growth, and emotional and behavioral outcomes. RESULTS Thirteen studies (2 randomized trials, 3 quasi-experimental studies, 8 cohort studies; N=775 children) were included in the review. Most studies using pre-post design indicated improvements in child development (with small to large effects, ds=0.007-1.132) and emotional and behavioral functioning (with most available effect sizes being large, ds=0.652-1.132). Comparison group studies revealed higher scores for infants of women in integrated programs than those not in treatment, with regard to development and most growth parameters (length, weight, and head circumference; with all available effect sizes being large, ds=1.16-2.48). In studies comparing integrated to non-integrated programs, most improvements in emotional and behavioral functioning favored integrated programs and, where available, most effect sizes indicated that this advantage was small (ds=0.22-0.45). CONCLUSIONS Available evidence supports integrated programs, as findings suggest that they are associated with improvements in child development, growth, and emotional and behavioral functioning. More research is required comparing integrated to non-integrated programs. This review highlights the need for improved methodology, study quality, and reporting to improve our understanding of how best to meet the needs of children of women with substance abuse issues.

OBJECTIVE Despite the widely held belief that abuse is a risk factor for childhood firesetting, the role of maltreatment in firesetting is largely unexplored. This study reports on a sample of children and adolescents referred to a brief assessment and intervention program for juvenile firesetters. Firesetting histories of maltreated youth were compared to a group of firesetting youth with no maltreatment history. METHODS Participants included 205 children and youth aged 4-17 years and their caregivers. Assessments were completed with a standardized protocol. Forty-eight percent of the sample had a history of maltreatment as reported by caregivers; 26% of the sample had experienced more than one type of maltreatment. RESULTS When compared to the non-maltreated group, children with histories of maltreatment demonstrated more frequent fire involvement, more versatility regarding ignition sources and targets, and a greater likelihood of an immediate family stressor as a motive for firesetting (all p<.05). Maltreated children were more likely to become involved with fire out of anger (p=.001), and there was also a trend towards higher rates of recidivism (p=.07). Childrens externalizing behavior partially mediated the influence of maltreatment on specific fire-related outcomes of children (OR=1.10; 95% CI=1.04-1.17; p=.001). CONCLUSIONS Within a juvenile firesetting population, the presence of maltreatment is a risk factor for a more severe course of firesetting. The findings also suggest that the link between maltreatment and firesetting is operating partially through heightened emotional and behavioral difficulties. PRACTICE IMPLICATIONS This study demonstrates that maltreatment is a risk factor that contributes to a more severe course of juvenile fire involvement, and that the link between maltreatment and firesetting operates largely through heightened behavioral and emotional difficulties. These findings highlight the need for mental health clinicians to (a) be aware that these two serious clinical issues frequently co-occur, (b) screen for fire-related behaviors and maltreatment during general assessments, and (c) consider maltreatment status when thinking about the risk of firesetting.

OBJECTIVE Despite high rates of firesetting among community adolescents, little is known about its correlates. This study identifies the mental health and substance use correlates of four firesetting levels in an epidemiological sample of adolescents. METHODS Three thousand, nine hundred and sixty-five (3,965) students in grades 7 to 12 were surveyed. Multinomial analyses were used to compare non-firesetters; desisters (lifetime, but no past-year firesetting); low frequency firesetters (once or twice in the past 12 months); and high frequency firesetters (3 + times) on measures of mental health and substance use. RESULTS Twenty-seven percent of youth reported firesetting during the past year. Of these, 13.7% reported one or two episodes, and 13.5% reported 3 or more episodes. Firesetting was more prevalent among males and among those in high school. Youth who began firesetting before age 10 were more likely to report frequent firesetting during the past year. Compared to non-firesetters, the firesetting groups had elevated risk profiles. Desisters and low frequency firesetters were more likely to report psychological distress, binge drinking, frequent cannabis use, and sensation seeking. Low frequency firesetters also reported higher rates of delinquent behavior, suicidal intent, and low parental monitoring than non-firesetters. High frequency firesetters reported elevated risk ratios for all of these risk indicators plus other illicit drug use. The cumulative number of risk indicators was positively associated with firesetting severity. CONCLUSIONS Firesetting is associated with psychopathology and substance use during adolescence. Findings highlight the need for programs to address the mental health and substance use problems that co-occur with firesetting.

BackgroundThere is a need for services that effectively and comprehensively address the complex needs of women with substance use issues and their children. A growing body of literature supports the relevance of integrated treatment programs that offer a wide range of services in centralized settings. Quantitative studies suggest that these programs are associated with positive outcomes. A qualitative meta-synthesis was conducted to provide insight into the processes that contribute to recovery in integrated programs and womens perceptions of benefits for themselves and their children.MethodsA comprehensive search of published and unpublished literature to August 2009 was carried out for narrative reports of womens experiences and perceptions of integrated treatment programs. Eligibility for inclusion in the meta-synthesis was determined using defined criteria. Quality assessment was then conducted. Qualitative data and interpretations were extracted from studies of adequate quality, and were synthesized using a systematic and iterative process to create themes and overarching concepts.ResultsA total of 15 documents were included in the meta-synthesis. Women experienced a number of psychosocial processes during treatment that played a role in their recovery and contributed to favourable outcomes. These included: development of a sense of self; development of personal agency; giving and receiving of social support; engagement with program staff; self-disclosure of challenges, feelings, and past experiences; recognizing patterns of destructive behaviour; and goal setting. A final process, the motivating presence of children, sustained women in their recovery journeys. Perceived outcomes included benefits for maternal and child well-being, and enhanced parenting capacity.ConclusionA number of distinct but interconnected processes emerged as being important to womens addiction recovery. Women experienced individual growth and transformative learning that led to a higher quality of life and improved interactions with their children. The findings support the need for programs to adopt practices that focus on improving maternal health and social functioning in an environment characterized by empowerment, safety, and connections. Womens relationships with their children require particular attention as positive parenting practices and family relationships can alter predispositions toward substance use later in life, thereby impacting favourably on the cycle of addiction and dysfunctional parenting.

BackgroundThe rate of women with substance abuse issues is increasing. Women present with a unique constellation of risk factors and presenting needs, which may include specific needs in their role as mothers. Numerous integrated programs (those with substance use treatment and pregnancy, parenting, or child services) have been developed to specifically meet the needs of pregnant and parenting women with substance abuse issues. This synthesis and meta-analysis reviews research in this important and growing area of treatment.MethodsWe searched PsycINFO, MedLine, PubMed, Web of Science, EMBASE, Proquest Dissertations, Sociological Abstracts, and CINAHL and compiled a database of 21 studies (2 randomized trials, 9 quasi-experimental studies, 10 cohort studies) of integrated programs published between 1990 and 2007 with outcome data on maternal substance use. Data were summarized and where possible, meta-analyses were performed, using standardized mean differences (d) effect size estimates.ResultsIn the two studies comparing integrated programs to no treatment, effect sizes for urine toxicology and percent using substances significantly favored integrated programs and ranged from 0.18 to 1.41. Studies examining changes in maternal substance use from beginning to end of treatment were statistically significant and medium sized. More specifically, in the five studies measuring severity of drug and alcohol use, the average effect sizes were 0.64 and 0.40, respectively. In the four cohort studies of days of use, the average effect size was 0.52. Of studies comparing integrated to non-integrated programs, four studies assessed urine toxicology and two assessed self-reported abstinence. Overall effect sizes for each measure were not statistically significant (d = -0.09 and 0.22, respectively).ConclusionsFindings suggest that integrated programs are effective in reducing maternal substance use. However, integrated programs were not significantly more effective than non-integrated programs. Policy implications are discussed with specific attention to the need for funding of high quality randomized control trials and improved reporting practices.

Psychological maltreatment in relation to substance use problem severity among youth.

Susan E. Rosenkranz; Robert T. Muller; Joanna Henderson

OBJECTIVES Research has demonstrated that experiences of childhood maltreatment are prevalent in the life histories of youth with substance use problems; however, most of this research has focused on sexual or physical abuse. The purpose of the current study was to extend the scope of previous investigations to include psychological maltreatment experiences, examining the extent to which emotional abuse and emotional neglect predict substance use problem severity among youth. The current study also sought to examine whether a cumulative model fit the data, in which the experience of multiple forms of maltreatment would be related most strongly to severity of substance use problems, or whether there was a distinct effect of psychological maltreatment. METHODS Data were collected through self-report questionnaires from 216 youth (144 males, 72 females) entering an outpatient treatment program for youth with substance use concerns. RESULTS Results indicated that, when considering all forms of abuse together, only emotional abuse and emotional neglect emerged as significant predictors of substance use problem severity. Furthermore, the association between psychological maltreatment and substance use problem severity was unaltered by the consideration of concurrent experiences of interpersonal violence. CONCLUSIONS The results of the current study are consistent with those of a body of research describing the detrimental effects of psychological maltreatment. The findings have potential implications for the development and provision of trauma-informed youth substance use treatment services. The findings suggest that attending to the sequelae of psychological maltreatment may be important in assisting these youth in achieving successful treatment outcomes.

Birth outcomes for infants born to women participating in integrated substance abuse treatment programs: A meta-analytic review

Karen Milligan; Alison Niccols; Wendy Sword; Lehane Thabane; Joanna Henderson; Ainsley Smith

Background: Infants born to women with substance abuse issues are at increased risk for prematurity, low birth weight, and impaired physical development. Integrated programs (programs that integrate on-site pregnancy-, parenting-, or child-related services with substance use treatment) have been developed to address these risks, barriers to accessing care, and the unique needs of pregnant women who abuse substances. Method: To examine the effects of integrated programs on birth outcomes, we compiled a database of 10 studies (N = 2471) of integrated programs published between 1990 and 2009 with birth outcome data. Data were summarized and meta-analyses were performed. Results: Compared to women with substance abuse issues not in treatment, women in integrated programs had infants with significantly higher birth weights, larger head circumferences, fewer birth complications, positive toxicology screens, and low birth weight classifications (ds = 0.42–0.87). Women in integrated programs attended significantly more prenatal visits (d = 2.20) and had significantly fewer pre-term births (d = 0.35) than women in non-integrated programs. Conclusions: This is the first systematic quantitative review of studies evaluating the impact of integrated programs on birth outcomes. Findings suggest that integrated programs may be associated with advantages over non-integrated programs in increasing womens participation in prenatal care and decreasing premature delivery. This review highlights the need for further research with improved methodology, study quality, and reporting to improve our understanding of how best to meet the needs of pregnant women with substance abuse issues.

To examine the impact of integrated treatment programs (those with substance use treatment and pregnancy-, parenting-, or child-related services) on maternal mental health, we compiled a database of studies of integrated programs published between 1990 and 2007 with outcome data on maternal mental health. There were 18 cohort studies, 3 randomized trials, and 2 quasi-experimental studies. Of the five studies comparing integrated to nonintegrated programs, three studies provided enough information to allow for them to be combined in a meta-analysis. The average effect size was 0.23 (95% CI = 0.15 to 0.31, SE = 0.04), p < .001. There was no statistically significant heterogeneity among the studies, Q = 5.66, p = .059. This meta-analysis is the first systematic quantitative review of studies evaluating the impact of integrated programs on maternal mental health. Findings suggest that integrated programs may be associated with a small advantage over nonintegrated programs in improving maternal mental health. This review highlights the need for further research with improved methodology, study quality, and reporting to improve our understanding of how best to meet the mental health needs of mothers with substance abuse issues.
