Relations between psychological birth order and life-style

The objectives of the master thesis “Relations between Psychological Birth Order and Life-Style” are to investigate the relations between psychological birth order and life-style, as well, to assess psychometric characteristics of the new Lithuanian version of the White-Campbell Psychological Birth Order Inventory (PBOI) after translation corrections of the previously translated (first) version of this questionnaire. 233 individuals (100 men and 133 women) were taken part in the analysis. 23 men and 30 women, to which the inventory was administered in previous analysis, were repeatedly assessed carrying out PBOI retest procedure after 3 weeks. Ages of the subjects ranged from 18 to 60 years (the mean age for subjects was 27.5 yr.). They were individuals from various Lithuanian localities, of different education and professions. Two techniques have been chosen to realize objective of this work: • White-Campbell Psychological Birth Order Inventory • Kern’s Life-style Scale. Before choosing these assessment techniques, it was collaborating with Assoc. Prof. A. Kepalaitė (Vytautas Magnus University, Kaunas) and M. Sc. L. Verseckaitė (Klaipėda University). They have permissions from authors of the mentioned questionnaires to use their instruments in Lithuania for scientific purposes. Research results suggest that psychological and actual birth order more often not coincide than coincide. The analysis supported a stronger relationship between psychological birth order and lifestyle than between actual birth order and life-style. The research also supported, that seeking perfection and need to please is characteristic for psychologically first males and females. Psychologically only males tend to self depreciate, and first females have unjustified expectations of self and others. The differences of life-styles among particular birth order positions were found: first children tend to be more perfectionistic than youngest and only ones; middle and only children tend to self depreciate than first and youngest ones; and middle males are more perfektionistic than youngest males
