Academic procrastination detrimentally affects students' other academic performances. Consequently, this study aimed to compare the effectiveness of instructional mental imagery and tolerance of ambiguity training on students' academic procrastination.

This quasi-experimental research involved two experimental groups and one control group, with a pre-test, post-test, and two-month follow-up design. The study population consisted of all female twelfth-grade students in both public and private schools in Bojnurd during the 2023-2024 academic year. The sample included 45 students selected through purposive sampling and randomly assigned into three equal groups (each group containing 15 students). The first experimental group underwent twelve 90-minute sessions of instructional mental imagery training, and the second experimental group received nine 90-minute sessions of tolerance of ambiguity training based on the cognitive-behavioral approach, while the control group received no training. Data were collected using the Solomon and Rothblum (1984) Academic Procrastination Questionnaire and analyzed using repeated measures ANOVA and Bonferroni post-hoc test in SPSS-25.

The findings indicated significant differences between groups in terms of reducing students' academic procrastination. Both the instructional mental imagery and tolerance of ambiguity training methods significantly reduced academic procrastination in the post-test and follow-up stages compared to the control group (P<0.05). Moreover, there was no significant difference between the instructional mental imagery and tolerance of ambiguity training methods in reducing students' academic procrastination (P>0.05).

Given the effectiveness of both instructional mental imagery and tolerance of ambiguity training methods in reducing students' academic procrastination, school counselors and psychologists can utilize these methods alongside other educational approaches to reduce academic procrastination.

The test anxiety has a great negative impact on other academic and non-academic variables, therefore, should look for educational and therapeutic solutions to reduce students' test anxiety. As a result, the current research was conducted with the aim of comparing the effectiveness of mental-grammatical imagery education and uncertainty tolerance education on students' test anxiety.

This was a semi-experimental study with two experimental groups and one control group, with a pre-test, post-test and two-month follow-up plan. In this study, the research population was all 12th grade female students of governmental and non-governmental schools in Bojnourd city in the 2022-2023 academic years. The sample of the present study was 45 students who were selected by purposive sampling method and randomly replaced in three equal groups (15 people in each group). The experimental group received 12 sessions of 90-minute with the mental-grammatical imagery education method, and the second experimental group received 9 sessions of 90-minute with the uncertainty tolerance education method based on the cognitive behavioral approach, and during this time, the control group did not receive any training. The data were collected with Sarason's test anxiety questionnaire (1985) and analyzed with the methods of analysis variance with repeated measure and Bonferroni's post hoc test in SPSS-25 software.

The findings showed that there was no significant difference between the groups in terms of reducing students' test anxiety (P>0.05). In addition, both methods of mental-grammatical imagery and uncertainty tolerance education significantly reduced students' test anxiety in the post-test and follow-up stages (P<0.001).

Considering the effectiveness of both methods of mental-grammatical imagery education and uncertainty tolerance education in reducing students' test anxiety, school counselors and psychologists can use mental-grammatical imagery education and uncertainty tolerance education methods to reduce test anxiety.
