The goal of this clinical trial is to assess whether an educational intervention based on the Health Belief Model (HBM) can effectively improve skin cancer protective behaviors, knowledge, and related health beliefs among female healthcare workers in Ahvaz, Iran. The main questions it aims to answer are: * Does the HBM-based educational program increase participants' knowledge about skin cancer, its risk factors, and preventive measures? * Does the intervention improve key HBM constructs such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action, leading to enhanced protective behaviors against skin cancer? Researchers will compare an intervention group receiving a multicomponent educational program-including seven 45-minute sessions delivered both in-person and via WhatsApp-tailored to HBM constructs, with a comparison group receiving no intervention, to determine the intervention's effectiveness. Participants will: * Attend structured educational sessions covering skin cancer symptoms, risks, prevention strategies, behavioral barriers, motivation, and self-efficacy enhancement, using multimedia tools and group discussions * Receive reminder messages and educational materials to facilitate behavior change * Complete validated questionnaires assessing knowledge, HBM constructs, and protective behaviors before the intervention and two months afterwards This study will evaluate if implementing a theory-driven, blended educational intervention can successfully promote protective behaviors and health beliefs related to skin cancer prevention among female healthcare workers.
This clinical trial study was conducted from 2022 to 2023 in health centers of Ahvaz, Iran, to evaluate the effectiveness of an educational intervention based on the Health Belief Model (HBM) in promoting skin cancer protective behaviors among female healthcare workers (HCWs). The study employed a two-group parallel design, randomly allocating 160 participants into an intervention group (n=54) and a comparison group (n=106). Eligible participants included female HCWs employed in the selected centers, with smartphone access and the ability to engage with digital educational content. The educational program was developed according to HBM constructs, including perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. The intervention consisted of seven 45-minute sessions delivered over two months using a blended approach combining in-person workshops and WhatsApp-based virtual education. Teaching methods included lectures, multimedia presentations, group discussions, motivational messaging, and reminder posters strategically placed in the workplace. The content was tailored based on baseline knowledge and behavioral assessments. Early sessions addressed skin cancer symptoms, risk factors, and complications to raise awareness and perceived risk. Subsequent sessions emphasized the advantages of protective behaviors, addressed and sought to reduce perceived barriers, and incorporated stress management and motivational techniques to enhance self-efficacy. Data collection employed a validated researcher-designed questionnaire covering demographic variables, knowledge about skin cancer, HBM constructs, and adherence to UV protective behaviors. Assessments were performed at baseline and two months post-intervention. Statistical analyses included descriptive statistics, Chi-square tests for categorical variables, and independent and paired t-tests to compare continuous variables within and between groups. Analysis of covariance (ANCOVA) controlled for confounding factors when evaluating intervention effects.

This blended educational intervention employs the Health Belief Model (HBM) to promote skin cancer preventive behaviors in female healthcare workers in Ahvaz, Iran. The 7-session program (each 45 minutes) combines in-person training with WhatsApp-based follow-ups. Participant Components: * Structured sessions targeting knowledge and HBM constructs such as perceived susceptibility, severity, benefits, barriers, self-efficacy, and cues to action. * Use of multimedia tools including videos, pamphlets, and interactive discussions. * Motivational messaging, stress management clips, and role-modeling techniques to build self-efficacy. * Visual cues such as posters placed in healthcare workplaces. * Daily reminder messages to reinforce behavior change. Unique aspects distinguishing this intervention include its specific tailoring for female healthcare workers in a high UV-exposure region, the combined digital and face-to-face delivery approach, and comprehensive focus on all HBM construc

Changes in Skin Cancer Protective Behaviors
Skin cancer protective behaviors among female healthcare workers were assessed using a validated, researcher-developed questionnaire. The instrument included multiple items evaluating behaviors such as applying sunscreen, wearing protective clothing (wide-brimmed hats, long-sleeved shirts, gloves), and using sunglasses. Responses were measured on a 5-point Likert scale ranging from 1 ("Never") to 5 ("Always"). Protective behaviors were expressed as the average score across items, with higher scores indicating more frequent and consistent engagement in skin cancer prevention practices.
Time frame: Baseline (pre-intervention) and 2 months post-intervention.
Changes in Cognitive-Behavioral Constructs Related to Skin Cancer Prevention
This outcome assesses changes in Health Belief Model (HBM)-based constructs related to skin cancer prevention, including perceived susceptibility (5 items; score range: 5-25), perceived severity (6 items; score range: 6-30), perceived benefits (5 items; score range: 5-25), perceived barriers (6 items; score range: 6-30), cues to action (4 items; score range: 4-20), self-efficacy (7 items; score range: 7-35), and knowledge (15 items; score range: 0-15). All constructs except perceived barriers were scored on a 5-point Likert scale ranging from "Strongly Agree" (score 5) to "Strongly Disagree" (score 1), where higher scores indicate more favorable outcomes such as greater perceived susceptibility, severity, benefits, self-efficacy, and cues to action. Items related to perceived barriers were reverse scored, so that higher scores indicate fewer perceived barriers. These constructs were measured using validated, researcher-developed questionnaires at baseline and two months after the inte
