A superiority of verbal intelligence over non-verbal intelligence, relative strengths in verbal memory and basic reading, and a relative weakness in visual/spatial memory are likely to be core characteristics of children/adolescents with 22qDS, transcending performance features that are typical of individuals with low IQ.
Interpersonal dependency in male perpetrators of intimate partner violence (IPV) is an understudied phenomenon but one that has noteworthy clinical implications. The present investigation used meta-analytic techniques to quantify the dependency-IPV link in all extant studies examining this relationship (n of studies = 17). Studies were gathered via an extensive literature search using relevant dependency/IPV search terms in the PsychInfo, Medline and Google Scholar databases. Results revealed a small but statistically significant relationship between dependency and perpetration of IPV in men (r = 0.150, Combined Z = 4.25, p < 0.0001), with the magnitude of the dependency-IPV link becoming stronger (r = 0.365, Combined Z = 6.00, p < 0.0001) when studies using measures of dependent personality disorder symptoms were omitted. Other moderators of the dependency-IPV effect size included IPV measure, type of sample and perpetrator age. These findings illuminate the underlying dynamics and interpersonal processes involved in some instances of IPV and may aid in understanding how to identify and treat male perpetrators of domestic violence.
These results support and extend analyses of the relationship between dependency and child maltreatment, and suggest that dependency may be both a precipitant of child maltreatment and consequence of victimization. Theoretical and clinical implications are discussed, with suggestions for further research outlined.
This study examined whether interpersonal dependency affects therapeutic outcome, using meta-analytic techniques to synthesize results from 31 studies (49 effect sizes; overall N = 3807). High levels of dependency were associated with more positive outcome in psychodynamic therapy (r = 0.11, p < 0.05), but not cognitivebehavioural therapy (r = À0.05, ns), and were associated with a less positive outcome in pharmacological treatment (r = À0.15, p < 0.001). Other predictors of outcome included patient diagnosis (high levels of dependency were linked with more positive outcome for patients with anxiety disorders but not those with depression), outcome measure (high levels of dependency were associated with significantly greater improvement in global functioning but not symptom reduction) and dependency measure (cognitive and cognitive-behavioural dependency scales yielded less positive results than other types of measures). These results contribute to a growing body of literature examining effects of personality on treatment process and outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
