Cognitive-behavioral therapy for individuals with chronic pain: efficacy, innovations, and directions for research

Over the past three decades, cognitive-behavioral therapy (CBT) has become a first-line psychosocial treatment for individuals with chronic pain. Evidence for efficacy in improving pain and pain-related problems across a wide spectrum of chronic pain syndromes has come from multiple randomized controlled trials. CBT has been tailored to, and found beneficial for, special populations with chronic pain, including children and older adults. Innovations in CBT delivery formats (e.g., Web-based, telephone-delivered) and treatments based on CBT principles that are delivered by health professionals other than psychologists show promise for chronic pain problems. This article reviews (a) the evidence base for CBT as applied to chronic pain, (b) recent innovations in target populations and delivery methods that expand the application of CBT to underserved populations, (c) current limitations and knowledge gaps, and (d) promising directions for improving CBT efficacy and access for people living with chronic pain.

Incapacitated rape and alcohol use in White and Asian American college women

This study examined the role of Asian ethnicity as a moderator of drinking outcomes associated with alcohol-related sexual assault (incapacitated rape). Participants were 5,467 Asian American and White college women. Results found the overall MANOVA for ethnicity and incapacitated rape (IR) interactions to be significant. Asian American participants with no history of IR had fewer drinking problems than White American participants with no history of IR. Asian American participants with IR histories had more drinking problems than White Americans with IR histories. Findings indicate Asian Americans who experience IR may be at increased risk for negative alcohol outcomes.

Effects of self-hypnosis training and cognitive restructuring on daily pain intensity and catastrophizing in individuals with multiple sclerosis and chronic pain

Fifteen adults with multiple sclerosis were given 16 sessions of treatment for chronic pain that included 4 sessions each of 4 different treatment modules: (a) an education control intervention; (b) self-hypnosis training (HYP); (c) cognitive restructuring (CR); and (d) a combined hypnosis-cognitive restructuring intervention (CR-HYP). The findings supported the greater beneficial effects of HYP, relative to CR, on average pain intensity. The CR-HYP treatment appeared to have beneficial effects greater than the effects of CR and HYP alone. Future research examining the efficacy of an intervention that combines CR and HYP is warranted.

Sex differences in pain and psychological functioning in persons with limb loss

Sex differences in pain are frequently reported in the literature. However, less is known about possible sex differences in the experience of pain secondary to a disability. The current study explored these issues in persons with limb loss (n = 335, 72% men) who were recruited as part of a postal survey. Participants provided ratings of phantom limb pain (PLP), residual limb pain (RLP), and general pain intensity. Participants also completed measures of pain-related interference, catastrophizing, coping, and beliefs. Results indicated that a greater proportion of males than females (86% vs 77%, respectively) reported the presence of PLP; however, this difference was no longer prominent when cause of limb loss was controlled. No sex differences were found in the presence of RLP, or in average intensity ratings of PLP or RLP. In contrast, females reported greater overall average pain intensity and interference than males. Females also endorsed significantly greater catastrophizing, use of certain pain-coping strategies, and beliefs related to several aspects of pain. This study did not find prominent sex differences in pain specific to limb loss. However, several sex differences in the overall biopsychosocial experience of pain did emerge that are consistent with the broader literature.

PERSPECTIVE

The current study contributes to the literature on sex differences in the experience of pain. Although males and females with limb loss did not significantly differ in their disability-specific pain, sex differences in their broader experience of pain were significant and are worthy of future clinical and empirical attention.

Identification with mainstream culture and preference for alternative alcohol treatment approaches in a community sample

Although various treatment approaches are available for alcohol problems, less than 25% of individuals with alcohol use disorders obtain treatment. The purpose of this study is to evaluate interest in attending alternative alcohol treatments, such as meditation and acupuncture, compared to Alcoholics Anonymous (AA). A community sample of 156 adult participants concerned about their drinking were recruited through flyers and newspaper advertisements to complete a Web-based survey assessing identification with mainstream culture, sexual identity, and likelihood to attend alternative alcohol treatments. Participants reported higher likelihood of attending alternative treatments as compared to AA, and lesbian, gay, and bisexual participants (28.2% of the sample) were more likely to attend alternative treatments than heterosexual participants. A series of regression analyses were conducted to test whether the relationship between sexual identity and likelihood to attend alternative treatments was mediated by identification with mainstream culture. Participants who were less strongly identified with mainstream culture, regardless of sexual identity, reported higher likelihood of attending alternative treatments. These findings highlight that, for certain subgroups of the population, alternative treatments for alcohol misuse are appealing and suggest the need for future research testing the efficacy of alternative treatments for alcohol problems.

Differential effects of acculturation on drinking behavior in Chinese- and Korean-American college students

OBJECTIVE

Recent evidence suggests increasing rates of alcohol use and related disorders among Asian-American young adults. Relatively little research has focused on this group, and few studies have examined heterogeneity in drinking prevalence and correlates across Asian subgroups. This study examined interactive effects of ethnicity, acculturation, and gender on drinking behavior among Asian-American undergraduates.

METHOD

Participants were 112 Chinese Americans and 108 Korean Americans (mean age = 19.2 years, 61% female) who completed measures of alcohol use, acculturation, and demographic factors. Multivariate analyses examined drinking behavior (defined as quantity, frequency, and duration) as a function of ethnicity, gender, and acculturation.

RESULTS

Overall, Korean ethnicity predicted increased drinking, and acculturation predicted decreased drinking. However, acculturation interacted with ethnicity such that its influence was protective for Korean Americans and negligible for Chinese Americans.

CONCLUSIONS

Previous research implicates acculturation as a risk factor for drinking among Asian Americans, but the current findings suggest that protective effects may also exist. Results also indicate that Korean ethnicity is a risk factor particularly in the context of low acculturation. These findings illustrate the need to consider ethnic subgroup differences in drinking rates and in risk and protective factors for alcohol use among Asian Americans.

The role of thought suppression in the relationship between mindfulness meditation and alcohol use

Previous studies have demonstrated that attempts to suppress thoughts about using substances may actually lead to increases in substance use. Vipassana, a mindfulness meditation practice, emphasizes acceptance, rather than suppression, of unwanted thoughts. A study by Bowen and colleagues examining the effects of a Vipassana course on substance use in an incarcerated population showed significant reductions in substance use among the Vipassana group as compared to a treatment - usual control condition [Bowen S., Witkiewitz K., Dillworth T.M., Chawla N., Simpson T.L., Ostafin B.D., et al. (2006). Mindfulness Meditation and Substance Use in an Incarcerated Population. Psychology of Addictive Behaviors.]. The current study further examines the mediating effects of thought suppression in the relationship between participation in the course and subsequent alcohol use. Those who participated in the course reported significant decreases in avoidance of thoughts when compared to controls. The decrease in avoidance partially mediated effects of the course on post-release alcohol use and consequences.

Domestic violence and alcohol use: trauma-related symptoms and motives for drinking

Alcohol use is frequently associated with posttraumatic stress disorder (PTSD), especially in the face of chronic traumatic experiences. However, the relationship between alcohol use and symptoms associated with chronic trauma exposure has not been evaluated. This study examined alcohol use in recently battered women (N=369). Differences were found in trauma symptoms between abstainers, moderate drinkers, and heavy drinkers, with heavy drinkers reporting more severe symptoms. Mediational analyses suggest that the relationship between drinking and trauma symptoms is mediated by drinking to cope, which has not been previously demonstrated in a battered population. Results suggest the importance of assessing trauma symptoms and motives for drinking in understanding alcohol use in recent survivors of domestic violence.

Mindfulness meditation and substance use in an incarcerated population

Despite the availability of various substance abuse treatments, alcohol and drug misuse and related negative consequences remain prevalent. Vipassana meditation (VM), a Buddhist mindfulness-based practice, provides an alternative for individuals who do not wish to attend or have not succeeded with traditional addiction treatments. In this study, the authors evaluated the effectiveness of a VM course on substance use and psychosocial outcomes in an incarcerated population. Results indicate that after release from jail, participants in the VM course, as compared with those in a treatment-as-usual control condition, showed significant reductions in alcohol, marijuana, and crack cocaine use. VM participants showed decreases in alcohol-related problems and psychiatric symptoms as well as increases in positive psychosocial outcomes. The utility of mindfulness-based treatments for substance use is discussed.
