investigate the effectiveness of Transactional Analysis training on perfectionism, academic engagement, and self-efficacy among high school students with anxiety symptoms

To evaluate the efficacy of Transactional Analysis (TA) training on reducing perfectionism and increasing academic engagement and self-efficacy among anxious students in Ahvaz.

A randomized, double-blind, parallel-group, controlled clinical trial, Phase 2, conducted on 60 students. Randomization was performed using block randomization with a block size of 4.

This randomized controlled trial was conducted at the Masir-e Roshd Psychology Clinic in Ahvaz. Participants were assigned to intervention and control groups, and data were collected in three phases. To minimize bias, the final evaluator was blinded to group allocation.

Inclusion criteria: Second-grade female high school students with high anxiety scores, providing informed consent from both parents and students. Exclusion criteria: Severe psychiatric disorders, active use of psychotropic medications, participation in other clinical trials, and underlying physical illnesses affecting anxiety.

Intervention Group: Students in the intervention group will receive an eight-session Transactional Analysis (TA)-based therapeutic intervention focused on identifying and modifying maladaptive ego states, psychological games, and life scripts associated with anxiety and perfectionism. The intervention aims to reduce anxiety symptoms, alleviate maladaptive perfectionistic tendencies, and enhance emotional regulation and self-efficacy. .Control Group: Students receive routine school counseling without any specific educational intervention related to TA.

Primary outcome: Maladaptive perfectionism score. Secondary outcomes: Academic self-efficacy score and psychological adjustment score of students.

Block randomization with a block size of 4 was used to ensure balanced allocation of participants between the intervention and control groups. The random allocation sequence was generated prior to the start of the study using SPSS software. After screening and confirmation of eligibility criteria, participants were enrolled sequentially and assigned a unique identification code. Eligible participants were then allocated to either the intervention or control group according to the pre-generated randomization list. To ensure allocation concealment, group assignments were placed in sequentially numbered, opaque, sealed envelopes. After a participant's enrollment was completed, the corresponding envelope was opened by a designated individual responsible for group allocation who was not involved in outcome assessment, and the participant's group assignment was revealed.

The shared dataset consists of "Anonymized Individual Participant Data" (IPD). This dataset includes demographic information, baseline characteristics, and all primary and secondary outcome variables measured in the study (specifically, scores for perfectionism, academic engagement, and self-efficacy). All potentially shareable data will be made available after the complete removal of personally identifiable information (such as names, national IDs, and phone numbers) and their replacement with random codes. Consequently, applicants will have access to all raw data related to the study variables, except for information that directly links to individual identities.

Access to the Individual Participant Data (IPD) will commence 6 months after the final results of the study are published in reputable scientific journals. This timeframe allows for the completion of initial analyses and the dissemination of primary findings; thereafter, qualified researchers may request access in compliance with ethical guidelines and data-sharing agreements.

Access to the study data is restricted to academic researchers, scientific investigators, and graduate students with relevant qualifications. Applicants must submit their requests via an official university or institutional email address, clearly outlining their research objectives. Individuals working in the industrial sector or non-academic organizations are eligible only if they are formal partners or collaborators of an educational/research institution, and their requests are approved by the principal investigator.

Access is conditional upon signing a Data Use Agreement (DUA) and committing to confidentiality and non-identification of participants. Commercial use is prohibited, and data usage is restricted to research purposes only. Furthermore, the principal investigator must be acknowledged as a co-author in all publications resulting from the use of this data.

To obtain the data, applicants must submit their request in writing to the principal investigator of the study. The preferred order of communication is as follows: first, sending an official email to [mortezaahmadi19922@gmail.com]; second, making a telephone call to [09166467276] during office hours; and third, sending correspondence by post to the address: [61349-37333]. All requests must include a scientific justification and, if necessary, ethical approval, and responses will be provided through the same channel used for the request.

Upon receipt of the formal request and signed Data Use Agreement (DUA), the principal investigator will evaluate the applicant's qualifications, including research objectives and ethical compliance. Once approved, the anonymized data will be securely shared via email in standard formats (e.g., CSV or SPSS). The entire process typically takes between 2 to 4 weeks.
