WHAT THE TEST MEASURES
About This Assessment
Diagnostic Questionnaire Loneliness: Type Test

Loneliness Type Diagnostic Questionnaire Test - Symptoms and Signs

This questionnaire provides a brief self-report screening of subjective loneliness and its presenting features. The Loneliness Type Diagnostic Questionnaire is intended to capture both current perceived social disconnection and qualitative patterns associated with the loneliness experience.

The measure includes 30 items and typically takes about 4 minutes to complete. Developed by Daniel Perlman and Letitia Anne Peplau, it may be used in clinical or research contexts to support case formulation and to monitor change over time. The Loneliness Type Diagnostic Questionnaire is not a stand-alone diagnostic instrument and should be interpreted in conjunction with clinical interview and other relevant assessment data.
