Lofexidine in Combination With Oral Naltrexone for Opioid Use Disorder Relapse Prevention: A Pilot Randomized, Double-Blind, Placebo-Controlled Study.

BACKGROUND AND OBJECTIVES: Lofexidine (LFX), an α2A adrenergic receptor agonist, known to alleviate opioid withdrawal symptoms, was assessed in combination with oral naltrexone (NTX) for effects on opioid use outcomes and NTX treatment compliance. METHODS: Detoxified individuals (ages 18-55, 80% male) with opioid use disorder Diagnostic and Statistical Manual of Mental Disorders, 4th edition were randomized to 2.4 mg/day of LFX (n = 26) or Placebo (PBO, n = 31) in a double-blind manner for 12 weeks of treatment. NTX compliance, opioid-free urine samples, opioid craving as well as vital signs, subjective opioid withdrawal symptoms were assessed. RESULTS: Intent to treat analysis revealed significantly better control over opioid craving in the LFX/NTX vs PBO/NTX group (P < .03), but no differences between groups in NTX compliance, opioid use, and overall opioid craving. However, subject withdrawal due to medication intolerance was significantly higher in the LFX/NTX (5/26) vs PBO/NTX (0/31) (P < .01). Two additional patients were withdrawn due to acute hepatitis infection. Post hoc secondary analyses with the nonwithdrawn sample indicated significantly higher rates of treatment completion (P < .05) and NTX compliance (P < .01), lower percent opioid urine samples (P < .05), and lower overall opioid craving (P < .05) in the LFX/NTX vs the PBO/NTX group. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Although preliminary, these findings suggest that LFX at doses up to 2.4 mg/daily was safe and improved control over opioid cravings. Among those who tolerated the medication, LFX/NTX significantly improved the opioid craving, delayed return to opioid use, and improved treatment compliance and completion rates. These findings support further assessment of LFX dose titration schedule along with the adjunctive use of LFX with NTX treatment to enhance opioid relapse prevention. (Am J Addict 2019;00:1-9).

Integration of movement competency training to optimize behavioral interventions for child obesity: Comment on Wilfley et al. (2018).

Wilfley, Hayes, Balantekin, Van Buren, and Epstein (2018) provided an important review of behavioral interventions for obesity in children and adults. Although behavioral change interventions are effective in increasing the frequency of exercise behaviors, behavioral treatment providers may not be experts regarding how fundamental movement/motor skills (FMS) deficits (e.g., ability to run, skip, balance, leap, kick, throw, catch, bounce) may hinder obese children from achieving physical activity goals. Prerequisite knowledge and skills are necessary to perform new target behaviors such as increasing physical activity, and exercise physiologists are best positioned to provide individualized exercise prescriptions to improve movement competence. Similar to psychologists and other behavioral treatment providers, exercise physiologists conduct their exercise interventions using an individualized, skills-building approach; by working collaboratively, behavioral health providers and exercise physiologists can develop integrative behavioral treatment plans to improve skills (both cognitive-behavioral and FMS) that may increase physical activity and improve health outcomes in children with obesity.

Death anxiety and ageist attitudes are related to trainees' interest in working with older adults.

OBJECTIVES: To explore how psychology trainee death concerns and ageist behavior relate to their willingness and desire to work with older adults. METHOD: Trainees (N = 104; 80.8% women) completed the Death Thought-Accessibility Measure, Relating to Older People Evaluation (ROPE), Death Anxiety Scale-Extended (DASE), and Beck Anxiety Inventory (BAI) and rated their willingness and desire to work with older adults and their willingness to obtain training on how to work with older adults. RESULTS: Pearson correlations showed that salience of death-related thoughts, death anxiety (but not general anxiety), and negative behaviors toward older adults were significantly negatively associated with trainees' willingness and desire to work with older adults. Regressions revealed that negative behaviors toward older adults was the strongest factor associated with willingness and desire to work with older adults, whereas positive behaviors toward older adults was the strongest factor associated with being willing to obtain training in working with older adults. Death anxiety and salience of death-related thoughts positively correlated with each other and were each positively associated with negative behaviors toward older adults. CONCLUSION: Helping graduate trainees become more comfortable with mortality and changing negative behaviors toward older adults may increase their interest in gerontology and geriatrics.

Differential Impact of Depressive and Manic Mood States on Alcohol Craving in Comorbid Bipolar Alcoholism: Preliminary Findings.

OBJECTIVES: To examine the differential impact of depressive and manic mood states on alcohol craving in patients with bipolar disorder and comorbid alcoholism. METHODS: Forty-four men and women, ages 18-65, with DSM-IV-TR comorbid diagnoses of bipolar I disorder and alcohol dependence were assessed over a three-month period to examine the extent to which their depressive and manic symptoms were associated with alcohol cravings (i.e., desire to use and not to use alcohol) at each assessment point, controlling for age, ethnicity, socio-economic status, baseline alcohol use, and number of assessments. RESULTS: Both manic and depressive symptoms were associated with greater desire to use alcohol. Only depressive symptomatology was associated with reduced desire not to use alcohol, and desire not to use alcohol declined over the course of the three-month treatment period. CONCLUSION: Whereas enhanced desire to drink alcohol may be a conditioned reaction to both manic and depressed mood states, desire not to drink alcohol may be more of an indicator of treatment motivation, which is negatively affected by depressed mood. Depressive symptoms may warrant prioritization and aggressive targeting early in treatment given that desire to refrain from alcohol use was only influenced by depressive symptoms and declined over the course of treatment.

How ineffective family environments can compound maldevelopment of critical thinking skills in childhood abuse survivors.

The high stress of childhood abuse is associated with neurobiological detriments to executive function. Child abuse survivors may also be cognitively and relationally disadvantaged as a result of being raised in emotionally impoverished families that lack cohesion, organization, flexibility, self-expression, and moral and ethical values and fail to provide opportunities for effective learning. A review of literature demonstrates how dysfunctional family of origin environments common to child abuse survivors, concomitant with the extreme stress of overt acts of abuse, can act as a barrier to the development of higher-order critical thinking skills. The article concludes by discussing ramifications of critical thinking skill deficits in child abuse survivors and highlights the importance of integrating and prioritizing critical thinking skills training in treatment.

A stress-coping profile of opioid dependent individuals entering naltrexone treatment: a comparison with healthy controls.

BACKGROUND: Stress is known to increase addiction vulnerability and risk of relapse to substance use. PURPOSE & METHOD: We compared opioid dependent individuals entering naltrexone treatment (n = 57) with healthy controls (n = 75) on measures of stress, coping, and social support and examined the relative contribution of group membership, coping, and social support to stress within the sample. Analyses of variance (ANOVA) and covariance (ANCOVA), and stepwise multiple regression were conducted. RESULTS: Compared with controls, opioid dependent subjects reported greater stress, less use of adaptive coping, but comparable use of maladaptive/avoidant coping. No group differences were found with respect to social support. Perceived stress was predicted by group membership, low social support, and greater use of maladaptive/avoidant coping, and the prediction by social support and maladaptive/avoidant coping did not differ by group. CONCLUSION: Opioid dependent individuals entering naltrexone treatment experience higher levels of stress and report less use of adaptive coping strategies when compared with controls. Group membership, maladaptive/avoidant coping, and social support independently contribute to perceived stress. Findings suggest that novel treatment approaches that decrease maladaptive/avoidant coping and improve social support are important aspects of decreasing stress during early recovery from opioid addiction.

Stress-related factors in cannabis use and misuse: implications for prevention and treatment.

We examined the role of stress as a risk factor and motivation for cannabis use/misuse. A systematic review of studies gathered from PsychINFO and MEDLINE databases was conducted. Findings suggest that cannabis is commonly used as a stress-coping strategy. Negative life events, trauma, and maladaptive coping were all related to consumption. Cannabis use for stress-coping purposes was most evident when examining chronic as compared with experimental use. Although many individuals may be able to use cannabis without consequences, there appears to be a subset of individuals who experience greater life stress and who may be more likely to use for stress-coping purposes. These individuals may be at greatest risk for addiction. Chronic use may potentiate stress-related motivation to use/abuse cannabis and is associated with decision-making deficits and alterations in brain-stress pathways that may exacerbate compulsive drug seeking and sensitize individuals to stress-related drug use. Overall, stress-coping interventions and harm reduction focused on reducing the amount ingested may facilitate prevention and recovery efforts.

Craving predicts time to cocaine relapse: further validation of the Now and Brief versions of the cocaine craving questionnaire.

BACKGROUND: The 10-item version of the cocaine craving questionnaire (CCQ-Brief) has not been validated in a mixed-gender sample, and predictive validity of the CCQ-Now and CCQ-Brief in terms of their relationship with cocaine relapse has not been demonstrated. OBJECTIVE: To further validate the CCQ-Brief in a mixed gender sample and to determine the predictive validity of the CCQ-Now and CCQ-Brief. METHOD: Seventy-two men and 51 women (Total N=123) seeking inpatient cocaine dependence treatment were administered assessments upon admission, and a prospective design was employed to assess cocaine relapse outcomes during a 90-day follow-up period after discharge from inpatient treatment. Data were analyzed using Pearson's correlation, Cox proportional hazards regression, and multiple regression. FINDINGS: The CCQ-Brief demonstrated good internal consistency and construct and concurrent validity. Both the CCQ-Now and the CCQ-Brief summary scores predicted time to cocaine relapse. In addition, the anticipation of a positive outcome from cocaine use, and intent and planning to use cocaine subscales of the CCQ-Now also predicted time to cocaine relapse. CONCLUSIONS: The CCQ-Brief was found to be a reliable and valid measure in a mixed gender sample, and both the CCQ-Now and CCQ-Brief were predictive of cocaine relapse risk. Craving assessments that go beyond desire and take into account intent and planning to use cocaine and the patient's anticipation of a positive outcome from using cocaine are likely to provide a sensitive index of cocaine relapse susceptibility. However, fear of social and clinical consequences could impact accurate reporting of cocaine craving and intent to use cocaine.

Severity of childhood trauma is predictive of cocaine relapse outcomes in women but not men.

We prospectively examined the gender-specific effects of childhood trauma on cocaine relapse outcomes in an inpatient sample of treatment engaged cocaine dependent adults. Cocaine dependent men (n=70) and women (n=54) participating in inpatient treatment for cocaine dependence were assessed on severity of childhood trauma and followed for 90 days after discharge from treatment. Greater severity of childhood emotional abuse was associated with an increased risk of relapse in women. Severity of emotional abuse, sexual abuse, and overall childhood trauma was associated with the number of days cocaine was used during follow-up in women, as was the association of severity of physical abuse and overall childhood trauma with the average amount of cocaine used per occasion. No associations between childhood trauma and cocaine relapse outcomes were found in men. These findings demonstrate that childhood trauma increases the likelihood of cocaine relapse and drug use escalation after initial relapse in women but not in men. Comprehensive assessments of childhood trauma and specialized treatments that address trauma-related pathophysiology could be of benefit in improving cocaine treatment outcomes in women.

Childhood maltreatment, perceived stress, and stress-related coping in recently abstinent cocaine dependent adults.

The authors examined associations between a personal history of childhood maltreatment and the perceived stress and stress-coping styles of recently abstinent and treatment-engaged cocaine dependent adults. Fifty men and 41 women at an inpatient treatment and research facility were administered the short form of the Childhood Trauma Questionnaire (D. P. Bernstein & L. Fink, 1998; D. P. Bernstein et al., 2003), the Perceived Stress Scale (S. Cohen, T. Kamarck, & R. Mermelstein, 1983), and the COPE Questionnaire (C. S. Carver, M. R. Scheier, & J. K. Weintraub, 1989). Simple and multiple linear regression analyses were used to analyze relationships while adjusting for relevant covariates. Findings indicate that overall childhood maltreatment severity was significantly associated with greater perceived stress and greater use of avoidance stress-coping strategies. These findings suggest that having a history of childhood maltreatment may influence how recently abstinent cocaine dependent individuals experience and cope with stress. Stress and stress-coping focused interventions may be particularly indicated for cocaine dependent individuals with histories of childhood maltreatment.

Stress and drug-cue-induced craving in opioid-dependent individuals in naltrexone treatment.

BACKGROUND: Naltrexone is a nonaddictive medication that blocks the euphoric effects of opioids. However, naltrexone treatment is associated with high rates of noncompliance and opioid relapse, possibly because it does not reduce stress and protracted withdrawal symptoms during early recovery. Prior clinical and preclinical research has indicated that both stress and drug-cue-related arousal response is associated with craving and vulnerability to relapse in a range of drug-using populations. AIMS: To examine opioid craving and the subjective and cardiovascular response to stress and drug cues in naltrexone-treated opioid abusers. METHOD: Eleven men and three women engaged in naltrexone treatment for opioid dependence. They were exposed to personalized stress, drug-cue, and neutral-relaxing imagery in a single laboratory session. Subjective (craving, emotion) and cardiovascular (heart rate, systolic blood pressure, and diastolic blood pressure) measures were assessed. RESULTS: Stress and drug-cue-related imagery significantly increased opioid craving, anxiety, and negative emotions and significantly decreased positive emotions compared to neutral imagery. Selective emotional responses were greater in the stress condition than in the drug-cue condition. Only stress-related imagery was associated with an increased cardiovascular response. CONCLUSIONS: Naltrexone-treated opioid abusers demonstrate vulnerability to stress and drug-cue-induced craving and arousal responses that may contribute to the high rates of noncompliance and relapse among opioid-dependent individuals undergoing naltrexone treatment. Pharmacological and behavioral interventions that specifically target the negative affectivity that co-occurs with drug-cue and stress-induced craving could be of benefit in improving naltrexone treatment outcomes in opioid dependence.

Gender specific associations between types of childhood maltreatment and the onset, escalation and severity of substance use in cocaine dependent adults.

We examined associations between types of childhood maltreatment and the onset, escalation, and severity of substance use in cocaine dependent adults. In men (n = 55), emotional abuse was associated with a younger age of first alcohol use and a greater severity of substance abuse. In women (n = 32), sexual abuse, emotional abuse, and overall maltreatment was associated with a younger age of first alcohol use, and emotional abuse, emotional neglect, and overall maltreatment was associated with a greater severity of substance abuse. There was no association between childhood maltreatment and age of nicotine or cocaine use. However, age of first alcohol use predicted age of first cocaine use in both genders. All associations were stronger in women. Findings suggest that early intervention for childhood victims, especially females, may delay or prevent the early onset of alcohol use and reduce the risk for a more severe course of addiction.

A gender specific psychometric analysis of the early trauma inventory short form in cocaine dependent adults.

This study evaluated the gender specific psychometric properties of the Early Trauma Inventory-Short Form (ETI-SF) in a clinical sample of cocaine dependent men (N=58) and women (N=34). Participants were administered the ETI-SF, the Childhood Trauma Questionnaire Short Form (CTQ-SF), and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Tests of internal consistency, convergent validity, and predictive validity were conducted separately by gender. Findings indicated that the ETI-SF demonstrated good internal consistency; Cronbach's alpha ranged from 0.73 to 0.80 for men and from 0.70 to 0.77 for women. The measure also demonstrated good convergence with the CTQ-SF in both sexes, indicating that reports of child maltreatment are consistent across interview and self-report measures. Further, predictive validity was demonstrated by the ability of various ETI-SF scales to predict the co-occurrence of psychiatric disorders commonly associated with early trauma. These included lifetime diagnosis of PTSD in men and women, the lifetime diagnosis of major depressive disorder in men, and the lifetime diagnoses of alcohol use disorders in women. The findings support the utility of the ETI-SF as a clinical research tool to obtain data on specific types of early trauma in drug abusing samples.

Family of origin environments in two clinical samples of survivors of intra-familial, extra-familial, and both types of sexual abuse.

OBJECTIVE: It has been suggested that survivors of ongoing childhood sexual abuse (CSA) tend to have been reared in ineffective family environments that render them particularly vulnerable to maltreatment and which foster psychological difficulties beyond those accounted for solely by their abuse. If this conjecture is valid, one would expect that the family of origin environments of CSA survivors would be disturbed whether their abuser was intra-familial or extra-familial. To assess this hypothesis, two studies compared the childhood family of origin environments and supportive parenting characteristics of a clinical sample of women sexually abused by family members only (the intra-familial group), by non-family members only (the extra-familial group), and by both family and non-family members (the "both" group). METHOD: Study 1 compared the three groups (total N = 213) using the Family Environment Scale (FES). Study 2 compared groups (total N = 86) on the positive parenting scales of the Exposure to Abusive and Supportive Environments Parenting Inventory (EASE-PI). RESULTS: In Study 1, multivariate analyses indicated significant differences on the independence, cohesion, and conflict subscales of the FES. Pairwise comparisons revealed that the extra-familial group reported significantly higher levels of family independence and lower levels of conflict than the other two groups. In addition, the extra-familial group reported higher levels of cohesion than the intra-familial group. However, the effect sizes of these comparisons were extremely small. In Study 2, multivariate analyses revealed no group differences on the EASE-PI scales. CONCLUSIONS: Low effect sizes on the three significant FES scales, non-significance on the remaining seven FES scales, and non-significance on the EASE-PI scales suggest that there is considerable similarity in the family of origin environments of adult female CSA survivors seeking therapy regardless of whether their perpetrators were family members, non-family members, or both family and non-family members.

Outcome research methodology of smoking cessation trials (1994-1998).

Although several reviews of smoking cessation trials have been published, none have specifically evaluated the adequacy of the studies' reporting practices in terms of describing the intervention and outcome variables used. This review evaluates the reporting procedures of 109 smoking cessation trials published in English language peer-reviewed publications from 1994 through 1998. MedLine and PsychLIT searches were used to identify potential studies. Each study was evaluated as to whether the following information was reported: (a) demographic characteristics, (b) pretreatment smoking variables, (c) study characteristics, (d) descriptions of the clinical trial, (e) follow-up procedures, and (f) posttreatment outcome measures. Although some areas of methodological strength were identified, inadequate reporting of pre- and posttreatment demographic and smoking variables was also evident. Based on this review, several areas in need of further research are identified and discussed. Lastly, consistent with other recent reviews of smoking cessation trials, this review concluded that the smoking field should consider delineating a uniform set of assessment and outcome measures and a minimum follow-up interval.
