Norm values and psychometric properties of the brief symptom inventory-18 regarding individuals between the ages of 60 and 95

Objective

The SCL-90 and the SCL-90-R are the most applied measures regarding psychological distress. To reduce and prevent an overload to of the individuals, the Brief Symptom Inventory with 18 items (BSI-18) was developed based on the SCL-90. Since psychological disorders more frequently occur at an older age, there is a growing need for efficient instruments to measure distress in the elderly. However, the BSI-18’s psychometric properties, norm values, and factorial structure have not yet been investigated in this age group.

Methods

The aim of this study was to evaluate the BSI-18 in a sample of elderly people and to establish norm values for this specific population. Subsequently, demographic information and BSI-18 results were collected from a sample totaling 884 (55% female, mean age of 70.75 years, SD = 7.08, age range = 60–95 years). The questionnaire contains three six-item scales: somatization (SOMA), anxiety (ANX), and depression (DEPR), which form a general symptom index (GSI).

Results

We found an acceptable to good model fit for a three-factor-model with a general GSI factor. The BSI-18’s psychometric properties were satisfactory. Strict measurement invariance was shown for age and gender. Additionally, we found differences in psychological distress based on sociodemographic variables.

Conclusions

These findings underline the growing need for preventive mechanisms for elderly people such as, e.g., (re)activating their social networks and strengthening their physical and psychological well-being.

Physical distress and relationship problems: exploring the psychosocial and intrapsychic world of suicidal geriatric patients

BACKGROUND

Suicide is a serious mental health problem in old age. Suicide ideation and life weariness are important psychopathological issues in geriatric medicine, although suicide ideation does not primarily depend on the severity of any physical disease. Despite these facts, insight into the internal psychological state of suicidal geriatric patients is still limited.

MATERIAL AND METHODS

This study examines intrapsychic and psychosocial issues in suicidal geriatric inpatients. A semistructured interview concerning suicide ideation in old age was used to interview 20 randomly chosen, acutely suicidal clinically geriatric inpatients aged 60 years and older. The control group comprised 20 nonsuicidal patients.

RESULTS

Hamilton Depression Scale 21 scores (HAMD 21; patient mean 17.3, control mean 6.1), suicidal ideation and psychiatric treatments differed significantly between the groups. In contrast to lifetime suicidal ideation, the discovery of a physical disease was the primary trigger for current suicidal ideation, followed by interactional conflicts. Patients would rather speak with family or friends than professionals about their suicidal ideation.

CONCLUSION

Suicidal ideation should be recognised as an important psychological problem in geriatric patients with interpersonal conflicts. Specific help and training for relatives is recommended.

Depressive symptoms and APOE polymorphisms in an elderly population-based sample

AIM

Apolipoprotein E (APOE) has been regarded as the principal susceptibility gene linked with Alzheimer's disease, also suggesting a relationship with depression in the elderly population. Thus, the purpose was to investigate the association of APOE polymorphisms with depression in elderly adults.

METHODS

APOE polymorphisms were determined in a Mexican population-based sample older than 60 years (n=1566) using 5' exonuclease TaqMan genotyping assays.

RESULTS

The distribution of the APOE allele and genotype frequencies was similar in patients with and without depression. There was no significant association between the presence of alleles or genotypes and depression and anxiety (Short Anxiety Screening Test) considering several combinations of other features. However, patients with the APOE*4 allele presented more thinking and concentration impairment than those patients with the APOE*3 allele.

CONCLUSION

Genetic variation at the APOE gene may contribute to some depressive symptoms in late-onset depression, rather than being a specific risk factor.
