Objective: At present, there are inconsistencies in the literature pertaining to the association between ADHD and problem gambling. This study utilized meta-analytic techniques to clarify the association between symptoms of problem gambling and symptoms of ADHD. Method: Several meta-analyses were conducted using a random effects model. PsycINFO, PubMed, ProQuest Dissertations & Theses, and Google Scholar were searched for relevant studies. Results: The weighted mean correlation between ADHD symptomology and gambling severity was r = .17, 95% confidence interval (CI) = [0.12, 0.22], p < .001. Mean age of the sample was the only moderator to approach significance, with greater age being linked to a stronger relationship between symptoms of ADHD and gambling severity. Conclusion: Clinicians needs to be cognizant of the greater risk of ADHD symptoms when working with problem gamblers and vice versa.

Coparenting refers to the way parents or caregivers relate to each other as parents. Marital satisfaction (MS) is the subjective evaluation of the overall quality of one's relationship, including the extent to which needs, expectations, and desires are met. The coparenting relationship is distinct from, yet intimately connected to, the marital relationship. The objective of this study was to summarize and analyze current evidence regarding the association between MS and coparenting quality (CQ). Meta-analyses of 108 published and unpublished articles were conducted to evaluate the association between MS and CQ. In the meta-analysis of samples including both mothers and fathers, a medium association was found between MS and CQ, r = .41; 95% CI [.37, .44]; Q(88) = 1253.42. Separate meta-analyses of samples including only mothers and only fathers and an analog analysis of variance examining the moderating effect of parent gender found larger effects for mothers (r = .48) than fathers (r = .42). Maternal age, paternal education level, relationship length, and number of children were also significant moderators, with larger effects being found with families with more advanced maternal age, lower paternal education, longer relationships, and more children. The country, person reporting on CQ, and measure of CQ were also found to be statistically significant moderators. This research has implications that may inform the work of parent and family support services and contribute to positive family functioning.
