WHAT THE TEST MEASURES

Loneliness Type Diagnostic Questionnaire Test - Description and methodology of the test

loneliness

social alienation

People who want to understand whether loneliness is mainly experienced as isolation, unstable connection, or inner conflict may use the Loneliness Type Diagnostic Questionnaire Test as a structured self-reflection exercise. This loneliness diagnostic questionnaire is intended for people who want a clearer picture of their interpersonal experience, not a label imposed from outside. Its result combines an overall indicator with several patterns that may guide further reflection.

What This Assessment Explores

The questionnaire treats loneliness as more than time spent alone. Its items cover belonging, perceived care, empathy, self-criticism, dependence on others’ moods, difficulty forming satisfying relationships, and feeling different from other people. Looking at different types of loneliness can show whether isolation is intertwined with alienation, inner conflict, or strained connection.

The result is organized into four dimensions:

Dissociated (0-15) reflects shifts between identifying with others and feeling alienated; Low 0-5, Moderate 6-10, High 11-15.
Alienating (0-15) reflects disconnection, reduced empathy or cooperation, and feeling unnecessary; Low 0-5, Moderate 6-10, High 11-15.
Diffuse (0-14) reflects suspiciousness, inner conflict, and seeking validation without genuine communication; Low 0-4, Moderate 5-9, High 10-14.
Loneliness (0-18) reflects the overall intensity of subjective isolation and limited emotional support; Low 0-5, Moderate 6-12, High 13-18.

Methodology and Scientific Basis

Each item uses a yes-or-no response, recording a direct self-report about experiences, beliefs, and relationship patterns. Responses are combined into four displayed totals, but the questionnaire does not state a point value for each answer. Results should therefore be read through the published ranges and bands rather than inferred from individual wording.

The framework is conceptually consistent with the Korchagina Loneliness Test (2008), which treats loneliness as multidimensional. Korchagina’s 2010 work and Plamadeala (2017) examine the value of distinguishing a general loneliness indicator from distinct forms. Perjan, Sanduleac, and Plamadeala (2017) used Korchagina’s scale alongside other measures when studying loneliness and self-actualization.

As a loneliness self-assessment, this online questionnaire is a structured reflection tool, not a newly validated clinical instrument. Its categories do not establish population norms, reliability coefficients, or diagnostic cutoffs for this version. Current mood, recent social events, self-awareness, and socially desirable responding may influence answers, so the profile is best read as a snapshot of perceived loneliness and relational experience.
