Previous investigators have reported a high prevalence of depressive symptoms in drug-dependent patients. Given the responsiveness of depressive disorders to both psychological and pharmacological treatments, it is desirable to find an economical, efficient screening instrument to detect depressive disorders in this population. In this study, 6 depression symptom screening scales (Beck Depression Inventory, Hamilton Depression Scale, Raskin Depression Scale, Degree of Illness Rating, Symptom Checklist 90 Overall, and Depression Subscale) based on either clinician interview or patient self report, were compared according to their utility in detecting cases of depression among 64 applicants for treatment at a substance abuse treatment unit of a community mental health center. The criteria for a case of depression were the Research Diagnostic Criteria (RDC) which are specified and operationalized. Cases identified using previously described cutoff scores on the screening scales were compared to rates based on the RDC and sensitivity and specificity were determined. The results showed that: (1) although the sensitivity of the symptom scales was applicable, ranging from 65--94%, the specificity was less impressive, ranging from 39--61%, and (2) the Beck Depression Inventory, a 13-item patient self report was the most sensitive and specific and is recommended for screening drug-dependent populations for depression.

Psychological investigations have failed to reveal a distinct personality type or psychodynamic conflict pattern in moderately and massively obese persons. Many of the psychological problems noted in the obese such as anxiety, depression, and poor self-esteem seem to be the result of, rather than the cause of, the obese state. Morbidly obese persons share an addictive behavior pattern that is also seen in persons with other types of addictions. The extent of their obesity points to the strong substance abuse component of the eating disorder. Behavior modification programs aimed at changing problematic eating patterns and teaching self-management skills in relation to food consumption have been moderately successful and have been shown to result in a mean post-treatment weiht loss of seven to 16 pounds. However, the majority of morbidly obese persons will not lose enough weight to make this an effective treatment program for them.

American Indians and Alaska Natives were the subject of a workshop sponsored by the National Institute of Mental Health and the Indian Health Service. Comorbidity of anxiety, depression, and substance abuse is highly prevalent in these two populations, and this was the focus of the meeting. This paper introduces the topic of psychiatric comorbidity, and considers the topics of culture, psychiatric diagnosis, and assessment. Future research directions and a brief summary of the papers presented at the workshop, which are included in this issue, are provided.

Depression, suicidality and substance abuse disorders are examined with special emphasis on the role of stressful life events in predicting severity and patterns of comorbidity among American Indian and Alaska Native adolescents in boarding school environments. Both amount and severity of comorbidity increase with age and specific patterns of comorbidity are associated with gender. Different types and amounts of stressful life events predict specific combinations of comorbidity. These outcomes are interpretable with respect to associated cultural dynamics and the ecology of mental health services delivery for Indian and Native adolescents. Theoretical and methodological issues are discussed in relation to the use of stressful life events in examining cultural factors related to comorbidity among culturally different populations.

Animal data indicate that serotonin (5-HT) is a major neurotransmitter involved in the control of numerous central nervous system functions including mood, aggression, pain, anxiety, sleep, memory, eating behavior, addictive behavior, temperature control, endocrine regulation, and motor behavior. Moreover, there is evidence that abnormalities of 5-HT functions are related to the pathophysiology of diverse neurological conditions including Parkinson's disease, tardive dyskinesia, akathisia, dystonia, Huntington's disease, familial tremor, restless legs syndrome, myoclonus, Gilles de la Tourette's syndrome, multiple sclerosis, sleep disorders, and dementia. The psychiatric disorders of schizophrenia, mania, depression, aggressive and self-injurious behavior, obsessive compulsive disorder, seasonal affective disorder, substance abuse, hypersexuality, anxiety disorders, bulimia, childhood hyperactivity, and behavioral disorders in geriatric patients have been linked to impaired central 5-HT functions. Tryptophan, the natural amino acid precursor in 5-HT biosynthesis, increases 5-HT synthesis in the brain and, therefore, may stimulate 5-HT release and function. Since it is a natural constituent of the diet, tryptophan should have low toxicity and produce few side effects. Based on these advantages, dietary tryptophan supplementation has been used in the management of neuropsychiatric disorders with variable success. This review summarizes current clinical use of tryptophan supplementation in neuropsychiatric disorders.

Selective serotonin reuptake inhibitors (SSRIs) are a recently developed class of drugs with significantly greater antidepressant efficacy than placebo. Generally, in double-blind comparative trials, all SSRIs demonstrated antidepressant efficacy similar to that of the 'standard' tricyclic antidepressants amitriptyline and imipramine; a meta-analysis of controlled trials found the efficacy of the SSRIs to be equivalent to that of the 2 tricyclics. Nevertheless, because of small patient numbers included in most studies that compare SSRIs with other antidepressants, no definitive statements about relative efficacy can be made. In these studies it is simply possible to state that no statistically significant differences were identified between SSRIs and the comparative antidepressants. Importantly, differences in clinical characteristics exist between the SSRIs-differences in elimination half-life (t1/2 beta) between fluoxetine and/or its metabolite (total t1/2 beta = 330 hours) and other SSRIs (t1/2 beta range = 15 to 30 hours), for example. This has implications in terms of potential drug interactions and must be considered when patients have to be switched to treatment with monoamine oxidase inhibitors. Studies with fluvoxamine have been conducted in both in- and outpatients, whereas trials with other SSRIs have been confined largely to outpatient populations. Fluvoxamine has been associated with a high incidence of nausea (37%), although this may have resulted from high initial dosages (rather than upward dose titration protocols) used in early trials. Of further interest, fluoxetine doses of 20mg may be sufficient to produce a satisfactory antidepressant response, and this SSRI may be particularly useful in patients with chronic retarded depression. More clinical data are required before the efficacy of sertraline and citalopram relative to standard antidepressants can be clearly defined. Preliminary data indicate that SSRIs are effective in the treatment of panic disorder, obsessive-compulsive disorder (OCD), eating (e.g. anorexia and bulimia) and personality disorders (e.g. anger, impulsiveness) and substance abuse (e.g. alcoholism); early results with fluvoxamine in the treatment of panic disorder and OCD, and with fluoxetine in the treatment of bulimia, personality disorders and alcohol abuse, have been encouraging. SSRIs have a more favourable tolerability profile than tricyclic antidepressants and, unlike the tricyclics, are not associated with anticholinergic adverse effects, sedation, cardiotoxicity or weight gain. SSRIs are associated with a relatively high incidence of nausea, particularly if high doses are used at the start of treatment. However, the incidence of nausea appears to decrease as treatment is continued.(ABSTRACT TRUNCATED AT 400 WORDS)

Eighty-two women, presenting as normal-weight bulimics, obese binge eaters, social phobics, and individuals with panic disorder, were compared on anxiety, depression, and substance abuse. All were administered the Anxiety Disorder Interview Schedule-Revised and completed the Michigan Alcohol Screening Test, Drug Abuse Screening Test, and Self-Consciousness Scale. A striking proportion of eating disorder subjects were comorbid for one or more anxiety disorders, the most frequent diagnoses being generalized anxiety disorder and social phobia. The results suggest that the place of anxiety in bulimia nervosa goes beyond that discussed within the context of the anxiety reduction model. Conflicting comorbidity findings among this and prior investigations are noted, however, and discussed in terms of the issue of differential diagnosis between eating and anxiety disorders.

Gender differences in the psychosocial correlates of suicidal ideation were studied. A sample of 613 high school students (ages 14-19) completed measures of suicidal ideation, depression, hopelessness, life stress, loneliness, alcohol and drug use, and reasons for living. The results of a discriminant function analysis indicated that males reported higher loneliness and substance abuse scores than females whereas females reported greater suicidal ideation, depression, and reasons for living. The results of multiple regression analyses found that, although the same four variables, depression, hopelessness, substance abuse, and few reasons for living emerged as significant predictors of suicidal ideation in both samples, the predictive equation accounted for more of the variance in ideation scores in females (57%) than in males (46%). In a final analysis a discriminant function analysis of the subscales of the reasons for living inventory revealed that females have a greater fear of death and injury whereas males have a greater fear of social disapproval over having suicidal thoughts. This may account for the greater rate of suicide completing among males. Fear of social disapproval, more anger and impulsivity, and less help-seeking behavior among males are offered as potential variables to explain the observed gender differences.

Recent research suggests that psychopathology, in particular depression and anxiety, differentially affects the substance abuse treatment response of men and women. This study explores the relationship between global psychopathology, depression, anxiety, and alcoholism treatment outcome. These variables were assessed in a sample of 507 (373 men; 134 women) substance abuse clients at intake and at a 6-month follow-up. With the exception of alcohol dependence, there were significant differences in the levels of alcohol problems, depression, anxiety, and global psychopathology for men and women at both intake and follow-up. For the whole sample and for men, initial levels of alcohol problems and alcohol dependence were the best predictors of alcohol problems at follow-up. For women, the initial levels of alcohol dependence and a global measure of psychological functioning were predictive of outcome at follow-up. These findings are compared with past research, and suggestions for further investigation are proposed.

Occupational therapists treating older people with Alzheimer disease know that they must also consider the others who are affected by the disease, the informal caregivers. Intervention is most effective when it enables both the impaired person and the primary caregiver to manage the secondary symptoms of dementia. Unfortunately, little is understood about how caregivers approach and carry out their tasks and about why male and female caregivers respond differently to their caregiving role in terms of depression, burden, stress, and substance abuse. This paper discusses the effects of gender on dementia management plans of spousal caregivers. Husbands and wives have different approaches to caregiving; each approach has consequences. Male caregivers adopt a task-oriented approach to their duties and carry out their activities in a linear fashion; female caregivers use a parent-child approach and nest activities inside one another in a constant stream of work. Two cases are presented to illustrate gender differences in dementia management plans. Implications for occupational therapy include suggestions for supporting men and women in their caregiving role, modulating the negative consequences of caregiving, and conducting research to demonstrate the efficacy of an occupational therapy approach.
