There is considerable interest in the relationship between interperson
al relationships and mood disorders. The Intimate Bond Measure (IBM) a
ssesses the respondent's perception of their partner over recent times
. IBM care scores have been reported to be independent of depression s
everity and personality, to distinguish between melancholic and non-me
lancholic depressives, and to predict treatment outcome. In a sample o
f 105 depressed patients, IBM care measures were independent of depres
sion severity and personality measures, but they did not distinguish b
etween melancholic and non-melancholic depressives, and did not predic
t treatment outcome. When the sample was restricted to individuals who
had been previously treated, IBM care measures did distinguish betwee
n melancholic and non-melancholic depressives, although they still did
not predict treatment outcome. Possible implications of these finding
s are discussed.
