Testing a Comprehensive Model of Muscle Dysmorphia Symptomatology in a Nonclinical Sample of Men (open access)

Testing a Comprehensive Model of Muscle Dysmorphia Symptomatology in a Nonclinical Sample of Men

As increasing emphases are placed on the importance of a muscular male physique in Westernized culture, more men are experiencing eating, exercise, and body image (EEBI) disturbances. Clinician-researchers have identified a syndrome, termed muscle dysmorphia (MD), in which individuals, usually men, are pathologically preoccupied with their perceived lack of muscularity. The current study tested a modified version of an extant theoretical model of MD symptomatology as well as an alternative model of MD symptomatology. Over 700 adult men completed a demographic questionnaire, a symptom inventory, a self-esteem questionnaire, a measure of perfectionism, a measure of the media’s influence on EEBI disturbances, and measures of body dissatisfaction and MD symptoms. Structural equation modeling (SEM) was used to examine the goodness of fit of the proposed models. Overall, the first model demonstrated poor fit with the data. Conversely, the alternative model fit the data adequately. The alternative model was cross validated with a second sample, and also fit this data adequately.

The Role of Experiential Avoidance in Trauma, Substance Abuse, and Other Experiences (open access)

The Role of Experiential Avoidance in Trauma, Substance Abuse, and Other Experiences

Experiential avoidance (EA) is a process in which a person attempts to avoid, dismiss, or change experiences such as emotions, behaviors, and thoughts. EA is associated with a number of psychological disorders and is generally harmful to psychological well-being. Various studies have explored the role of EA as a mediator, while others have studied EA as a moderator. The current study aimed to further understand and broaden the knowledge of the role of EA in regard to trauma, substance abuse, aggression, and impulsivity by examining relationships between these variables with EA as a mediator and as a moderator. Experientially avoidant behaviors (i.e., substance abuse, aggression, and impulsivity) were related to higher levels of EA. EA was found to partially mediate the relationship between the number of traumatic experiences and posttraumatic stress disorder (PTSD) symptoms, as well as the relationship between substance abuse and PTSD. EA was also found to moderate the relationship between PTSD symptoms and aggression. Findings from the present study as well as its limitations and future directions for research are discussed.

Harmony Or Discord: Disordered Eating and Personality Traits of College Music Majors (open access)

Harmony Or Discord: Disordered Eating and Personality Traits of College Music Majors

Personality traits, such as neuroticism, perfectionism, and a narrow self-concept have been identified as risk factors for eating disorders or have been found at higher rates in those with eating disorders (e.g., Brannan & Petrie, 2008; Cash & Deagle, 1997; Cervera et al., 2003). Musicians exhibit many of these personality traits associated with eating disorders (e.g., Kemp, 1981), however eating disorder prevalence has not been studied in musicians. The present study examined the prevalence of eating disorders and pathogenic weight control behaviors among college music majors. This study also compared personality traits (i.e., neuroticism, perfectionism, musician identity) between music majors and nonmajors and examined which personality traits best predicted bulimic symptomatology. Participants were 93 female and 126 male undergraduate students majoring in music and a nonmusician comparison group of 310 women 140 men from the same university. Music majors and nonmajors did not differ from each other with regards to eating disorder prevalence rates. Exercising and fasting/strict dieting were the primary means of weight control amongst all participants. With regards to personality traits, female and male music majors reported higher levels of perfectionism than their nonmajor counterparts and male music majors reported higher levels of neuroticism than male nonmajors.

Predictors of Hiv-related Neurocognitive Impairment in an Hiv/aids Population (open access)

Predictors of Hiv-related Neurocognitive Impairment in an Hiv/aids Population

Although, in the United States HIV infectivity has increased, survival rates have also improved due to highly active antiretroviral therapies (HAART). Adherence to HAART successfully prevents the progression of AIDS and AIDS-related morbidity for many living with HIV. Unfortunately, HAART’s permeability into the central nervous system (CNS) is limited; thus, the prevalence of HIV-associated neurocognitive disorders (HAND) still persists. The health belief model (HBM) is the theory often used to explain and predict behavior in relation to chronic illness. This model incorporates perceptions of susceptibility, vulnerability, and severity towards a particular illness, and beliefs regarding perceived efficacy and benefits of treatment. This study expands the existing model. Many who live with HIV have a long history of negative experiences, such as stigmatization, traumatic events, and discrimination. I examined supplementary psychosocial and physiological predictor variables, such as stigma, trauma, ethnicity, general medical conditions, HIV-opportunistic infections, and falls; all relevant to disease progression in HIV. Previous researchers found links between stigma and immune function, trauma and memory, ethnicity and neuropsychological impairment, and symptom load and CNS-related alterations. Therefore, this study examined how these different psychosocial predictor variables are associated with HIV-related neurocognitive impairment. My model explained 38.6% of the variance in the …
