Objective

To examine among immigrants and others seeking primary care: (1) the prevalence, types, and predictors of traumatic life events; and (2) the relations among traumatic life events, psychiatric disorders, and utilization of primary care services.

Design

Survey with structured diagnostic interview.

Setting

Community-based, university-affiliated primary care clinic in southern California.

Participants

Fourteen hundred fifty-six adult patients representing 4 ethnic groups (Mexican immigrants, Central American immigrants, US-born Latinos of Mexican descent, and US-born non-Latino whites).

Dependent measures

Rates of traumatic events measured with the Posttraumatic Stress Disorder section of the Diagnostic Interview Schedule; psychiatric disorders identified by the Composite International Diagnostic Interview using Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition criteria; physical functioning (Short Form Health Survey); and the number of medical clinic visits during a 6-month period.

Results

Nearly 10% of patients had experienced a traumatic event in the previous year, and 57% had experienced at least 1 during their lifetimes. The most common forms of trauma were interpersonal violence occurring outside the family (21%), acute losses or accidents (17%), witnessing death or violence (13%), and domestic violence (12%). When compared with the US-born non-Latino whites, Mexican immigrants were half as likely, and Central American immigrants were 76% more likely, to report having experienced a traumatic event. Married individuals were significantly less likely to report traumas. Traumatic experiences, female gender, and non-Latino ethnicity were associated with the presence of a psychiatric disorder. One-year and lifetime psychiatric disorders were associated with poorer physical functioning and an increased number of clinic visits during a 6-month period.

Conclusions

Traumatic life events are common and associated with psychiatric disorders other than posttraumatic stress disorder in an ethnically diverse sample of primary care patients. Psychiatric disorders, in turn, are strongly associated with poor physical functioning and higher rates of primary care utilization. Screening for traumatic experiences should accompany assessments of psychiatric disorders to ensure adequate treatment of patients seeking primary care services.

This study used a clustering model, Hierarchical Classes Analysis (HICLAS), to examine patient groupings in a multiethnic sample of 1456 patients using primary care services at a university-affiliated community clinic in southern California. Somatic symptoms, psychiatric diagnoses and disability were studied using a survey instrument that included portions of the Composite International Diagnostic Interview (CIDI), the Diagnostic Interview Schedule (DIS) and the RAND-MOS Short Form Health Survey's (SF-36) 'physical functioning' dimension. HICLAS identified 11 clusters of patients with distinct patterns of medically unexplained somatic symptoms. These patient clusters varied with respect to psychiatric diagnoses and symptoms, gender, immigration status and disability. Results of this study suggest that the type of presenting symptom(s) and their various combinations may have diagnostic and prognostic value in primary care settings. These new findings may lead to further refinement of current diagnostic constructs for somatizing syndromes.

The interdependent adjustment of children and their parents following disasters has been well documented. We used the Actor-Partner Interdependence Model (APIM) to provide an appropriate analytical framework for examining how family members may contribute to each other’s post-disaster mental health. Independent self-reports were collected from parent–child dyads (n = 397) residing in a rural community in Indonesia that was devastated by a major earthquake. Elementary school children (M = 10 years; 51 % female) and one of their parents (M = 41 years; 73 % female) each reported on their disaster exposure, posttraumatic stress (PTS) symptoms, and general distress. The APIM was used to examine mental health within dyads and moderation by gender across dyads. Children reported lower disaster exposure and fewer PTS symptoms, but similar general distress levels, as their parents. Children’s and parents’ disaster-specific PTS symptoms were the strongest predictor of their own general distress. Parents’ PTS symptoms were associated with children’s general distress (b = 0.14, p < 0.001), but children’s PTS symptoms were not associated with parents’ general distress (b = −0.02, p > 0.05). Findings were not moderated by parents’ or children’s gender. Although children and parents may respond differently to natural disasters, they may be best understood as a dyad. APIM analyses provide new evidence suggesting a unidirectional path of influence from parents’ disaster-related symptomatology to children’s general mental health. Dyadic approaches to understanding mental health and treating symptoms of distress among disaster survivors and their families following trauma are encouraged.

Background

Somatisation is a common and frustrating clinical problem in primary care.

Method

Using structural diagnoses and functional measures, we examined the prevalence and associated features of somatisation disorder defined by three current nosologies and an abridged construct in subjects using primary care services.

Results

Somatisation disorder, diagnosed according to the standard criteria, was found to have a very low prevalence (range 0.06-0.5%), while more than one-fifth of the sample (22%) met the criteria for the abridged diagnosis. There was poor agreement between succeeding versions of the DSM system for identifying cases of somatisation disorder, each system ending up with rather disparate sets of individuals as well as variable levels of psychopathology and disability.

Conclusions

According to these data, standard somatisation disorder diagnoses add little to the prediction of disability/psychopathology beyond the contributions of an abridged construct of somatisation.
