Estimating perceived parental substance use disorder: Using register data to adjust for non-participation in survey research

Problematic parental substance use, childhood family structures and adverse outcomes in young adulthood

Aim: The aim of the present study was to investigate the association between childhood family structures, including the presence or absence of problematic parental substance use (PPSU), and adverse outcomes during adolescence/young adulthood. Methods: The study population included 9,770 young people (aged 15-25 years) from samples drawn for two national surveys in Denmark during 2014-2015. By combining surveys with national register data, five types of childhood family structures were constructed based on whether the child experienced PPSU and/or family separation and the number of years the child lived with a parent with substance use problems. Using binary logistic regression models, the relationships between family structure and adverse outcomes in young adulthood (i.e., hospital admissions, mental disorders and criminality) were investigated. Results: Young people who experienced PPSU and did not live with both parents had higher odds of the different long-term adverse outcomes compared with young people who did not experience PPSU, and similar odds of the outcomes compared to youth who had not experienced PPSU and did not live with both parents. The highest odds of adverse outcomes were found among young people who experienced PPSU and lived with the parent with substance use problems for less than five years. Conclusions: Living with both parents protected against adverse outcomes in young adulthood, and if PPSU was present, the odds of adverse outcomes increased. The hypothesis that there would be a positive association between years living with a parent with substance use problems and adverse outcomes in young adulthood was not supported. Awareness should be raised in health service, educational and legal institutions about the risk for young people from families with PPSU who do not live with both parents.

The impact of parental substance use disorder and other family-related problems on school related outcomes

Aims

To identify young people with different levels of family-related problems, including parental substance use disorder (PSUD), and investigate differences in grades at graduation from compulsory school and further enrollment in education.

Methods

Participants included 6784 emerging adults (aged 15-25 years) from samples drawn for two national surveys in Denmark 2014-2015. Latent classes were constructed using the following parental variables: PSUD, offspring not living with both parents, and parental criminality, mental disorders, chronic diseases and long-term unemployment. The characteristics were analyzed using an independent one-way ANOVA. Differences in grade point average and further enrollment were analyzed using linear regression and logistic regression, respectively.

Results

Four classes of families were identified: 1. "Low adverse childhood experiences (ACE) families", 2. "Families with PSUD", 3. "Families with unemployment" and 4. "High ACE families". There were significant differences in grades, with the highest average among youth from "Low ACE families" (males = 6.83; females = 7.40) and significant lower averages among both males and females from the other types of families, but lowest among young people from "High ACE families" (Males = 5.58; females = 5.79). Youth from "Families with PSUD" (Males: OR = 1.51; 95% CI: 1.01-2.26; females: OR = 2.16; 95% CI: 1.22-3.85) and "High ACE families" (Males: OR = 1.78; 95% CI: 1.11-2.26) were significantly more likely not to be enrolled in further education compared with "Low ACE families".

Conclusions

Young people who experience PSUD, both as the primary family-related problem as well as among multiple family-related problems, are at increased risk for negative school-related outcomes.
