The UPPS-P (Urgency-Premeditation-Perseverance-Sensation Seeking-Positive) impulsive behavior scale score will be used to evaluate the link between atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived downtime (continuous variable) on the ICJE score (continuous variable). The UPPS-P Impulsive Behavior Scale is a 59-item self report scale to assess impulsive personality. The scale can be used with adults or adolescents (ages 13+) to identify the separate personality facets that have been previously lumped together under the term "impulsivity".

Interaction between the score on the Difficulties in Emotion Regulation Scale (DERS) scale, the presence of atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived downtime (continuous variable) on the ICJE score (continuous variable).

The DERS is a 36-item a measure designed to assess clinically relevant difficulties in emotion regulation and provides valuable insights into an individual's ability to understand, accept, and manage emotions effectively. The 36 questions can be answered by Almost Never, Sometimes, About half the time, Most of the time or Almost always with scores ranging from 1 - 5 for each answer.

Interaction between the Generalized Anxiety Disorder 7-item (GAD-7) scale score, the presence of atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived downtime (continuous variable) on the ICJE score (continuous variable). The GAD 7 is an easy-to-perform initial screening tool for generalized anxiety disorder. Comprising seven items, the GAD-7 measures the frequency of anxiety symptoms over the past two weeks, with respondents rating each item on a scale from "not at all" to "nearly every day."

Interaction between the Patient Health Questionnaire (PHQ) 9 score, the presence of atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived downtime (continuous variable) on the ICJE score (continuous variable)

Interaction between the Gambling Quality of Life Scale -brief (GQoLS-Brief) brief scale score, the presence of atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived inactivity time (continuous variable) on the ICJE score (continuous variable). The GQoLS -brief assesses the impact of gambling disorder (GD) on quality of life (QoL) and contains questions scored on a 4-point Likert scale.

G. Interaction between the Gambling Attitudes and Injunctive Norms Scale scale score, the presence of atypical working hours (dichotomous variable "yes/no" + if "yes": categorical variable: working hour categories) and perceived inactivity time (continuous variable) on the ICJE score (continuous variable).The Gambling Attitudes and Injunctive Norms Scale (GAINS; Neighbors et al., 2007) was developed to examine relationships among injunctive norms and college student gambling. The 32-item scale consists of sixteen attitudinal items, asking participants about their approval or disapproval of students engaging in different gambling behaviors. Mean score for the sample on these items serves as the actual injunctive norms comparison. The remaining 16 perceived injunctive norms items ask "How do you think most college students feel about other students' gambling behavior?" The items consist of a 5-point Likert scale ranging from "Strongly Disapprove" to "Strongly Approve."
