The use of IOC significantly improves clinical, behavioral, and psychological determinants of periodontal health 4 months after treatment.

Objectives. This study investigates the joint role of coping planning and action control as volitional predictors of changes in the daily consumption of fruit and vegetables.Design. In a longitudinal online survey, 203 participants completed assessments at baseline (Time 1), 1 week (Time 2), and 2 weeks later (Time 3).

Health messages are a commonly used way to promote changes in dietary habits but their efficacy could be enhanced by strategies such as the way in which the presented arguments are framed. This study aimed to test the effectiveness of framed messages (gain vs. loss) on behavioural intention and fruit and vegetable (FV) intake, comparing predictions based on prominent theoretical perspectives on message framing (function of the health behaviour and recipients' motivational orientation) and by further exploring the role of baseline intentions as a potential moderator of the framing effects. Undergraduate students (N = 180) completed the three assessment points in time. At baseline, individual moderators (motivational orientation and intentions) and fruit and vegetable intake were assessed. One week later, participants were randomly assigned to the loss or gain-framed message and indicated their intentions for FV intake the following week. A week later, FV intake over the previous week was assessed. The gain-frame was not conducive, per se, to higher intentions or behaviour. Having intention as the outcome, only baseline intentions moderated the effects of message frame. When considering FV intake as the outcome, both motivational orientation and baseline intentions moderated the effects of message frame, with the loss-frame promoting higher FV intake among individuals who were prevention-oriented and had higher baseline intentions. Findings suggest that the success of framed messages for FV intake depends upon the recipient's characteristics, such as motivational orientation, baseline intentions, and cultural background, with implications for health communication interventions.

To bridge the intention-behavior gap, preparatory behaviors play a mediating role, and they represent a side of planning that constitutes the most proximal predictor of condom use.

Aim: This study investigates the joint role of volitional predictors of oral hygiene behaviours of flossing and brushing in adults with gingivitis, framed by the Health Action Process Approach model (HAPA). Materials and Methods: In a longitudinal online survey, 201 participants aged 18-75, of which 56.7% were women, completed assessments at baseline(T1), 2 weeks(T2) and 4 months(T3). Oral hygiene behaviours(OH) (brushing and flossing) and social cognitive determinants of behaviour in the HAPA: action and maintenance selfefficacy(ASE & MSE), intention(INT), coping planning(CP) and action control(AC) were evaluated. Structural equation modelling was used to test a series of three nested models. In Model 1, action self-efficacy would determine MSE and INT, and INT would determine OH; in Model 2, INT would determine both CP and AC and the two OH behaviours; and in Model 3, CP and AC would be sequential mediators between INT and OH.Results: Model 3, predicting a mediating process from intention to behaviour via coping planning and action control, showed the best fit according to the fit indices and explained more of the variance in dental hygiene. The mediating role of coping planning and action control between intention and oral hygiene behaviours was thus confirmed. Importantly, coping planning did not mediate between intention and oral hygiene behaviours, which means that oral hygiene intention influences action control through coping planning, and both sequentially mediate this influence on behaviour. Conclusions: For individuals who are not yet following the recommendations for specific oral hygiene behaviours, coping planning and action control represent psychological mechanisms by which intentions are put into practice.
