Participants will be administered the Cyberchondria Severity Scale Short Form (CSS-12), Health Perception Scale, and State and Trait Anxiety Scale online via Google form.

The Cyberchondria Severity Scale (CSS) was originally developed by McElroy and Shevlin (2014) to evaluate cyberchondria, defined as a form of anxiety characterized by excessive health-related information seeking on the internet. Subsequently, McElroy et al. (2019) introduced the short form of the scale, the CSS-12. The Turkish adaptation, validity, and reliability study of the CSS-12 was conducted by Söyler et al. (2021).

The CSS-12 consists of 12 items, each rated on a 5-point Likert-type scale ranging from 1 ("never") to 5 ("always"). Total scores are calculated by summing all item responses, with possible scores ranging from 12 to 60. Higher scores indicate greater severity of cyberchondria. The scale does not contain any reverse-coded items. The CSS-12 comprises four subdimensions: excessiveness, distress, reassurance-seeking, and compulsion.

The Health Perception Scale (HPS) was developed by Diamond et al. in 2007 to assess individuals' perceptions of their own health. The Turkish adaptation, including validity and reliability testing, was conducted by Kadıoğlu et al. in 2012. The scale consists of 15 items rated on a 5-point Likert-type scale, with response options ranging from "Strongly Disagree" to "Strongly Agree." Negative items are reverse-coded (Strongly Disagree = 5 to Strongly Agree = 1). The scale includes four subdimensions: central control, self-awareness, certainty, and importance of health. Total scores range from 15 to 75, with higher scores reflecting a more positive health perception. Participants indicate their agreement with each item, allowing researchers to quantify their overall health perception and examine its relationship with other psychosocial variables.

The State-Trait Anxiety Inventory (STAI) was originally adapted into Turkish by Öner and Le Compte between 1974 and 1977 to evaluate anxiety levels in both adolescent and adult Turkish populations. The inventory is widely used in research involving young and adult groups. The State Anxiety Scale items assess the intensity of feelings or behaviors in response to specific situations, with responses rated on a 4-point scale: 1 = Not at all, 2 = Somewhat, 3 = Much, 4 = Completely. The Trait Anxiety Scale items evaluate the frequency of feelings or behaviors over time, with response options: 1 = Almost never, 2 = Sometimes, 3 = Often, 4 = Almost always. The State Anxiety Scale consists of both direct items (3, 4, 6, 7, 9, 12, 13, 14, 17, 18) and reverse-scored items (1, 2, 5, 8, 10, 11, 15, 16, 19, 20). Similarly, the Trait Anxiety Scale includes direct items (22, 23, 24, 25, 28, 29, 31, 32, 34, 35, 37, 38, 40) and reverse-scored items (21, 26, 27, 30,
