Metacognition and Health Anxiety: A prospective Study.16 3.3 Prospective Moderator Analysis To explore whether metacognitive beliefs at time 1 prospectively moderated the relationship between catastrophic misinterpretation and health anxiety, a moderation model was tested with a moderator of the effect of X (catastrophic misinterpretation-time 1: CABAH1) on Y (health anxiety-time 2: WIT2) by M (metacognition-time 1: MCQ-HA Total1). Using Process (command model-1), a computational bootstrapping tool for path analysis based moderation (Hayes, 2012), the moderator effect was highly significant B = 0.0646, 95% CI [0.02, 0.10], t = 3.13, p < .005. Exploration of the conditional effect of X on Y at values of the moderator, revealed the following: 1. When MCQ-HA total T1 is low there is a non-significant negative relationship between catastrophic misinterpretation T1 and health anxiety T2. B = - 0.1566, 95% CI [-0.4299, 0.1167], t = -1.1368, p = .2584. 2. At the mean value of MCQ-HA total T1 there is a non-significant positive relationship between catastrophic misinterpretation T1 and health anxiety T2. B = 0.1765, 95% CI [-0.0734, 0.4265], t = 1.4016, p = .1642. 3. When MCQ-HA total T1 is high there is a strong significant positive relationship between catastrophic misinterpretation T1 and health anxiety T2. B = 0.5096, 95% CI [0.1350, 0.8843], t = 2.699, p = .0082. The simple slopes analysis (Figure 1) depicts these interaction effects. It is only when MCQ-HA total is high that the prospective relationship between catastrophic misinterpretation and health anxiety strengthens and becomes significant. In essence this

Metacognition and Health Anxiety: A prospective Study.17 prospective moderation means that in order for misinterpretation to cause subsequent health anxiety, metacognitive beliefs must be highly elevated at the same time. Of the individual subscales of the MCQ-HA, only “beliefs about uncontrollability” emerged as a significant prospective moderator, B = 0.1331, 95% CI [0.01, 0.25], t = 2.12, p =.035.

Metacognition and Health Anxiety: A prospective Study.18 It is important to establish if the moderator effects obtained with metacognition is specific to this dimension or is a feature of other health-related (cognitive-level) beliefs. To explore this, a further model was tested with a moderator of the effect of X (catastrophic misinterpretation-time 1) on Y (health anxiety-time 2) by M (dysfunctional beliefs-time 1).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
