    Significance and Rationale For Study

    Women seek helpmen die.

    This conclusion was drawn from a study of suicide prevention by Angst & Ernst(1990). They found that 75% of those who sought professional help in an

    institution for suicide prevention were female. Conversely 75% of those whocommitted suicide in the same year were male.

    Since depression is a significant risk factor for suicide and men receive lesstreatment for depression than do women, it is vitally important that we have abetter understanding of the way depression manifests itself in males.

    Research Hypotheses

    There will be a significant positive relationship between typical

    depression (CES-D) and atypical depression (DMDS).

    Depressed men will score significantly higher for atypical symptoms(DMDS) than depressed women.

    Non-depressed men will score significantly higher for atypical symptoms(DMDS) than non-depressed women.

    There will be a significant relationship between known depressive riskfactors and atypical depression.

    There will be a significant positive relationship between atypicalsymptoms (DMDS) and suicide risk.

    Atypical symptoms of depression will be positively related to suicide riskwhen controlled for typical depression.

    There will be a significant positive relationship between atypicalsymptoms (DMDS) and scores on the Gotland scale.

    Atypical Symptoms of Depression and Known Depressive Risk Factors

    There was a negativerelationship between atypical depression (DMDS) factorsand the following risk factors:

    Age ( Factor 1, p = < .001, Factor 2, p = < .001, Factor 3, p = < .001) Gross family income ( Factor 1, p = .015, Factor 2, p = .001,

    Factor 3, was not significant). Relationship happiness ( Factor 1, p = < .001, Factor 2, p = < .001,

    Factor 3, p = < .001).

    There was a positiverelationship between atypical depression (DMDS) factorsand the following risk factors:

    Comorbid medical conditions ( Factor 1, p = < .001, Factor 2, p = .001,Factor 3, p =.006).

    Having relatives who were depressed ( Factor 1, p = .034,Factor 2, p = .031, Factor 3, p =.002).

    The forth hypothesis, There will be a significant relationship betweenknown depressive risk factors and atypical depression, was answeredaffirmatively for the risk factors previously noted.

    Implications for Theory

    This study adds to the body of knowledge regardinggender and depression. By evaluating a larger set ofatypical depression symptoms (DMDS) than hadpreviously been used by Rutz (1999) with the GotlandScale for Assessing Male Depression, the study added toour understanding of male-type depression.

    The study expands our understanding of therelationship between gender and atypical symptoms fordepression. It addressed a gap in the research literatureon gender and depression by clarifying three separatefactors or subscales that are associated with depressionand suicide risk.

    Potential Bias

    There were selection biases since the study population was recruited throughwebsites that were focused on people with an interest in gender issues anddepression and thus not representative of the general population.

    There were measurement biases since assessment of important variables such asdepression and suicide risk were based on respondents answers to an on-linequestionnaire. No outside, professional assessments were conducted.

    Subjects were rated as being depressed or non-depressed based on their answersto a traditional depression scale (CES-D). Since one of the theoretical assumptions ofthe study was that depressed males might be missed using a traditional scale, this

    may have introduced additional measurement bias.

    Recommendations for Future Research

    Future research will be needed to validate the results of thestudy and to develop numerical scores for evaluatingdepression and suicide risk using the DMDS.

    It would be helpful to conduct research with a generalpopulation to see if results were consistent in a populationrepresentative of the general community. Particular attentionshould be focused on including men and women from differentethnic groups, cultural backgrounds, economic levels, and agegroups.

    Recommendation for Clinical Practice

    The belief that depression is a disease primarily affecting women has left toomany males undiagnosed and untreated.

    Many clinicians believe that depressed males are undiagnosed because theevaluation scales being used do not address the symptoms of depression thatare more common in men.

    Based on the results of the present study, it is recommended that cliniciansuse scales that include atypical symptoms such as those found on the DMDSand Gotland Scales.

    Surprises

    Though the study was originally designed for U.S. clients, men andwomen from 44 other countries participated.

    Based on clinical experience it was expected that it would bedifficult to recruit depressed males. This was not the case.

    Only Factor 1, Emotionally-Acting In, was significantly related tosuicide risk when all three factors were used together.

    There was actually a negative relationship between suicide risk andFactors 2 and 3, though the relationship was not significant.

    Thank You!

    The three of you, each in your own way,

    have made this study much better than itwould have been.
