Personality disorders and social support in cannabis dependence: A comparison with alcohol dependence.

ABSTRACT:

Background

Cannabis use disorder (CUD) has been linked to personality disorders (PDs) and interpersonal problems, though these relationships have been understudied. We examined PDs and social support associated with cannabis dependence and how it may be distinguishable from alcohol dependence on these indices in a large representative sample.

Method

Data on social support and Diagnostic and Statistical Manual of Mental Disorders-IV substance dependence and PDs were assessed in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N > 34,500).

Results

Cannabis dependence was associated with higher rates of personality disorders and lower social support. Lifetime cannabis dependence without alcohol dependence was associated with higher rates of all PDs than alcohol dependence without cannabis dependence (with the exception of borderline PD). Cannabis dependence alone was also associated with lower social support than alcohol dependence alone.

Limitations

The survey was conducted in 2004-2005 and relied on DSM-IV criteria.

Conclusions

These findings highlight a broad range of PDs as well as deficits in social support in cannabis dependence. The potential interrelationships between interpersonal dysfunction and CUD as well as the relevance of PDs to treatment for CUD warrant further research.

Project description:The present study examined the association between personality pathology (PP) and alcohol dependence (AD; both lifetime and in the past 12 months) among middle-aged to older adults incorporating three sources of assessment, specifically, diagnostic interviews as well as self- and informant reports. We collected data from a representative sample of community participants (N = 1,630; ages 54-65 years) and their informants (N = 1,462). Measures employed were the substance use disorder sections of the Mini-International Neuropsychiatric Interview Schedule for Mental Disorders, the Structured Interview for DSM-IV Personality (American Psychiatric Association, 2000, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., text rev.; DSM-IV-TR SIDP) and the NEO-Personality Inventory-Revised (Costa, P. T., & McCrae, R. R., Revised NEO-Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) manual, 1992, Odessa, FL, Psychological Assessment Resources; self-report and informant versions). To complement the diagnostic interview for personality disorders (PDs), we utilized a PD-count technique derived from the five-factor model (FFM), which provided an index of PP liability. Factors representing lifetime and past-12 month AD were regressed on each of the 10 PP factors constructed from the SIDP interview, as well as self-report and informant FFM-count scores. Lifetime diagnosis of AD was positively associated with higher scores on several PP measures, including paranoid, schizotypal, antisocial, borderline, histrionic, and narcissistic PP. There was an inverse relation between lifetime AD and the factor score for obsessive-compulsive PP. With regard to AD in the past 12 months, antisocial, borderline, histrionic, and narcissistic PP factors were significantly associated with increased risk for AD, whereas the obsessive-compulsive and schizoid PP factors were associated with decreased risk for AD. The present data indicate that features of antisocial and borderline PP continue to exhibit a relatively strong association with risk for AD in later middle age.

Project description:ObjectiveOver the past decade, cannabis use has become increasingly popular in states that include Colorado. During this time, alcohol use disorders (AUDs) and alcohol-related medical conditions have also been consistently recognized as public health problems with increasing prevalence in the state. Despite the widespread use of cannabis in Colorado, the epidemiology of cannabis use among those with AUDs has been poorly described. Therefore, we sought to examine cannabis use among individuals with likely AUDs and individuals with low-risk alcohol use during a time of major Colorado legislative changes before and after legalization of recreational cannabis in 2012.MethodsThis study was a secondary data analysis conducted with information from 303 participants (80% male) in the Denver, CO metropolitan enrolled between August 2007 and April 2016 for studies related to alcohol and lung health. Of these participants, 188 (62%) were completing inpatient alcohol detoxification with likely AUDs. All participants completed the Alcohol Use Disorder Identification Test (AUDIT) to establish their likelihood of an AUD, and all had information on current cannabis use assessed by questionnaire and urine toxicology testing.ResultsIndividuals with likely AUDs more commonly used cannabis compared to control participants (42% vs 27%, p = 0.007). In multiple logistic regression analyses, participant type (likely AUD versus control), tobacco smoking, and age were significantly associated with cannabis smoking; however, the year of participant enrollment was not. Adjusted odds for cannabis use among participants with likely AUDs were 2.97 (1.51-5.82), p = 0.002, while odds for cannabis use among tobacco smokers were 3.67 (1.94-6.93), p < 0.0001. Among control participants, tobacco smoking increased odds of cannabis use seven-fold.ConclusionsOur findings highlight the exceptionally high odds of cannabis use among individuals with likely AUDs undergoing alcohol detoxification at a Colorado treatment facility before and after legalization of recreational cannabis. Targeted investigations into the medical and psychiatric consequences of combined alcohol and cannabis use are urgently needed to define its health impact in these vulnerable individuals.
