In 2002, Boholst constructed a Life Position Scale to finish his dissertation. The construct life position was one of the variables he studied in his doctoral dissertation titled, The Influence of Life Scripts and Life Positions on Psychopathology and Positive Mental Health: A Structural Equation Modeling. He had to construct this scale because no one was available at the time. In 2005, he and two other authors wrote another article that found modest correlations between Life Positions and Attachment Stylesvalidating the scale by establishing the relationship between life positions and a variable that was theoretically argued to have conceptual parallels or to be "similar" with it. In 2012, Isgor and two other authors translated the Life Position Scale into Turkish and established its reliability and validity.

This is often a realistic scenario where a tool slowly attains credibility through a gradual validation process across the yearsoften by different authors. For example, in 2004, Weisner wrote his doctoral dissertation at the University of North Texas on the relationship between Affective Traits and Life Positions. Hadzi-Pesic and others more recently (2014) validated the Life Position Scale and found correlations with alcohol addicts' personalities.

How can I discuss the different types of validity that have been employedwhether implicitly or explicitly to validate the life position scale? It is ideal, therefore, to read articles in chronological order, starting with the A Life Position Scale, Life Positions and Attachment: A Canonical Correlation Analysis, and Life Positions Scale Language Equivalence, Reliability, and Validity Analysis.
