The relationship between time perspective and professional self-determination in male and female adolescents: sex differences

<jats:p>&lt;p&gt;&lt;strong&gt;Context and relevance.&lt;/strong&gt; The study focuses on the sex differences in the structure of the connection between professional self-determination and the perception of lifetime (time perspective) in adolescence, which remains under-researched within the event-biographical framework. &lt;strong&gt;Objective.&lt;/strong&gt; The aim is to identify the sex differences in relationships between dynamic parameters of time perspective and professional self-determination. &lt;strong&gt;Hypothesis.&lt;/strong&gt; There are significant sex differences in the structure of relationships between time perspective parameters, measured within the event-biographical approach, and professional choice. &lt;strong&gt;Methods and Materials. &lt;/strong&gt;The study involved 156 people aged 14 to 28 (M = 18,69; Me = 18; SD = 4,20), including 78 boys and 78 girls. The Life Line method (A.A. Kronik) was used to analyze the time perspective, while the Self-Determination Test (E.A. Osin) and the Subjective Quality of Educational Profile Choice Questionnaire (D.A. Leontiev) were used to analyze the parameters of professional choice. &lt;strong&gt;Results.&lt;/strong&gt; Significant sex differences have been identified in the relationships between dynamic temporal parameters (such as expected life span and the structure of event connections) and professional choice. A key finding is the ambivalent role of expected life span in girls: it is positively associated with satisfaction with their choice and autonomy, but negatively with self-reliance. In male adolescents, this predictor is positively associated with all aspects of choice. Also, among boys, choice parameters are significantly related to age identity and negative past experience, reflected in the structure of causal connections, which is not observed in girls. &lt;strong&gt;Conclusion.&lt;/strong&gt; The dynamic perception of time, assessed through the system of event connections, is a significant, but differently structured, factor in the professional self-determination of male and female adolescents, which requires the development of differentiated approaches to their psychological and pedagogical support.&lt;/p&gt;</jats:p>
