Evaluation of the short form of "Experience in Close Relationships" (Revised, German Version "ECR-RD12") - A tool to measure adult attachment in primary care

Attachment theory helps us to understand patients´ health behavior. Attachment styles might explain patient differences in coping behavior, self-treatment, or patient-provider relationships. In primary care time constrains are relevant. A short instrument may facilitate screening and assessment in daily medical practice. The aim of this study was to evaluate a 12-item short version of the Experience in Close Relationships-revised (ECR-R-D) to be used in primary care settings. We included 249 patients from ten general practices in central Germany into a cross-sectional study. Exploratory factor analysis was performed to evaluate the factor structure of the ECR-items. Cronbach's alpha was used to assess internal consistency. The results related to the short form of the ECR are in line with those of the German full-length version of the measure (ECR-RD 36). Internal consistencies were in an adequate range. The ECR short form can be recommended as a screening measure of attachment styles in primary care.

Two is a perfect number: Patient–doctor relationship and patient attachment style in palliative care

We tested the association between the palliative patient’s attachment style and the patient–doctor relationship, by means of Revised Adult Attachment Scale and a self-designed, patient–doctor relationship questionnaire. The study included 110 (52 M, 58 F) cancer, hospice patients, aged 36–80 years. We observed 54 percent of secure, 18 percent of dismissive, 9 percent of preoccupied, and 19 percent of fearful styles. Securely attached patients developed significantly ( p < .05) better relationships with doctors than insecure patients. There was no difference in the quality of the patient–doctor relationship among dismissive versus preoccupied versus fearful patients. We argue that attachment theory should be applied in palliative care to improve patients’ quality of life and dying.

Food allergy and attitudes to close interpersonal relationships: An exploratory study on attachment

BACKGROUND

Food allergy is a common immunologic disease that includes potentially fatal reactions. It impacts considerably on patients' social life including close interpersonal relationships. Attachment theory provides a theoretic framework to evaluate the quality of close interpersonal relationships in chronic disorders. Attachment insecurity, mainly characterized by attachment avoidance, has been found in a variety of health conditions, but still needs to be investigated in food allergy. The study aimed to investigate attachment, as attitude to close interpersonal relationships, among food-allergic young patients, compared to healthy controls.

METHODS

This is a cross-sectional study involving patients suffering from IgE-mediated food allergy sequentially recruited and matched to healthy controls for age and gender. The Attachment Style Questionnaire (ASQ) was used to assess five factors and two attachment dimensions (Anxiety-Avoidance). Associations with anaphylaxis and adrenaline prescription were explored among patients.

RESULTS

174 participants were assessed (female=45%; mean age=17.51; SD=4.26). Food-allergic patients reported significantly higher levels of Discomfort with Closeness (P<.05), Relationships as Secondary (P<.05) and Attachment Avoidance (P<.0001) compared to controls.

CONCLUSIONS

Clinicians should be aware of implications of insecure attachment for health and illness. They should support patients in limiting social impairment finding a balance between safety and psychologic well-being.

Validating a Patient-Reported Comorbidity Measure with Respect to Quality of Life in End-Stage Renal Disease

Purpose

Medical record-derived comorbidity measures such as the Charlson Comorbidity Index (CCI) do not predict functional limitations or quality of life (QoL) in the chronically ill. Although these shortcomings are known since the 1980s, they have been largely ignored by the international literature. Recently, QoL has received growing interest as an end-point of interventional trials in Nephrology. The aim of this study is to compare a patient-reported comorbidity measure and the CCI with respect to its validity regarding QoL.

Methods

The German Self-Administered Comorbidity Questionnaire (SCQ-G) was completed by 780 adult end-stage renal disease-patients recruited from 55 dialysis units throughout Germany. Acceptance was evaluated via response rates. Content validity was examined by comparing the typical comorbidity pattern in dialysis patients and the pattern retrieved from our data. Convergent validity was assessed via kappa statistics. Data was compared to the CCI. Linear associations with QoL were examined (criterion validity).

Results

The SCQ-G was very well accepted by dialysis patients of all ages (response rate: 99%). Content validity can be interpreted as high (corresponding comorbidity items: 73.7%). Convergent validity was rather weak (.27≤ρ≤.29) but increased when comparing only concordant items (.39≤ρ≤.43). With respect to criterion validity, the SCQ-G performed better than the CCI regarding the correlation with QoL (e.g., SF-12-physical: SCQ-G total score: ρ = -.49 vs. CCI: ρ = -.36).

Conclusions

The patient-reported measure proved to be more valid than the external assessment when aiming at insights on QoL. Due to the inclusion of subjective limitations, the SCQ-G is more substantial with respect to patient-centered outcomes and might be used as additional measure in clinical trials.
