One hundred and twenty-nine participants ranging in age 18 to 68 years old (M = 31.73, SD = 9.884) participated in the study. They were required to complete a battery of questionnaires including Defense Style Questionnaire (DSQ-40), UCLA Loneliness Scale Version 3 and Inclusive General Trust Scale (IGTS). Multiple linear regression analyses showed that the use of adaptive defense mechanism, anticipation are positively associated with trust while maladaptive defense mechanism, projection and somatization are negatively associated with trust. The use of adaptive defense mechanisms is negatively associated with loneliness while the use of maladaptive defense mechanisms, projection, autistic fantasy and isolation are positively associated with loneliness. Possible rationale of these findings are discussed. Implications for client interview and interventions are suggested.enDefense MechanismsLonelinessTrustProjectionAutistic FantasyIsolationSomatizationAnticipationThesis
