- The aim, design and setting of the study:
The current study was a cross-sectional and descriptive-correlational study conducted from April 2023 to January 2024, aiming to determine the PSA and PST among Iranian parents of children and adolescents with CD. The research was carried out in the psychiatric clinics of Imam Hussein Hospital in Tehran, Iran.
- The characteristics of participants:
The participants in the present study consisted of one parent of each child and adolescent aged 6 to 17 years with conduct disorder (CD) who referred to the psychiatric clinics of Imam Hossein Hospital in Tehran in order to screen their children and adolescents for the existence of CD. The diagnostic screening process for CD was implemented based on the psychiatrist's opinion, medical records and history, and the “Rating Scale for Diagnosis of Conduct Disorder (RSDCD).” Afterward, the sample size for the current study was calculated based on the study of Hasani et al. (33) using the following formula:
$$\:n=\frac{{{z}^{2}}_{1-\alpha\:/2\:}\times\:\:{\sigma\:}^{2}}{{\delta\:}^{2}}$$
Hence, from the initial 108 parents of children and adolescents with a definitive diagnosis of CD, only 79 individuals were simultaneously eligible based on the inclusion criteria of the study and provided their consent after being informed about the conditions and objectives of the study. Eventually, a final number of 60 individuals completed the entire questionnaire.
- Description of process:
In order to initiate the data collection process, approval from both the ethics committee of Shahid Beheshti University of Medical Sciences (SBMU) and the vice-chancellor of SBMU was acquired. Then, obtaining verification from the education department of Imam Hossein Hospital was considered. Afterward, the process of selecting the participants for the present study was implemented based on the inclusion criteria and a convenience sampling method by both authors of the current study. Accordingly, based on the inclusion criteria, the parents (either father or mother) must have children or adolescents aged 6 to 17 years with Conduct Disorder (CD, based on the psychiatrist's opinion, medical records, and the RSDCD) who have been diagnosed with CD for at least one year. Moreover, neither the parents nor their children or adolescents should have severe physical or psychocognitive disorders that may interfere with their participation in the present study (which has been specified according to the diagnosis of clinics’ psychiatrists, the self-report of the participants and their medical history). Furthermore, it was necessary for all participants to have sufficient skills in communicating in Persian. Ultimately, the principle of voluntary participation of the participants was mandatory.
Reciprocally, according to the exclusion criteria, participants who left more than 10% of the questionnaires unanswered were excluded from the study.
Subsequently, following the determination of the final participants, the questionnaires “Socio-Demographic Information Questionnaire (SDIQ),” “Dibble and Cohen Parent Report (DCPR),” and “Kansas Parental Satisfaction Scale (KPSS)” were presented to them along with comprehensive explanations. Additionally, as mentioned earlier, the RSDCD was also presented to the parents in order to measure the severity of CD among their children and adolescents.
Accordingly, the “SDIQ” was designed by the authors and consisted of the sociodemographic information of both parents and their children and adolescents with CD. To evaluate the validity of the SDIQ, the method of qualitative content validity was implemented.
The DCPR, as the second tool of the present study, was designed by Dibble and Cohen in 1974. The DCPR consisted of 23 items, and its purpose was to measure the Parent Satisfaction Tool (PST) in two conditions: the “current PST” and the “Ideal PST (IPST).” The scoring method of the DCPR was in the form of a 7-point Likert scale for the options of “never (score: 0),” “almost never (score: 1),” “seldom (score: 2),” “half the time (score: 3),” “frequently (score: 4),” “almost always (score: 5),” and “always (score: 6).” Accordingly, the total score of the DCPR, ranging from 0 to 46, indicated “inappropriate PST,” a score between 47 and 69 indicated “average PST,” and finally, a score higher than 69 indicated “appropriate PST.” The reliability of the DCPR has been evaluated by the method of “test-retest” between the responses of fathers and mothers, which was 87.5% for “current PST” and 81.25% for “IPST” (34). Moreover, it is essential to indicate that the validity of the DCPR has been confirmed by many studies (35–38).
The next tool of the current study was the KPSS. The KPSS was designed by Schumm and Hall in 1985 to evaluate the Parental Satisfaction Assessment (PSA). The KPSS consisted of 3 items that express the levels of PSA on a 7-point Likert scale from “extremely dissatisfied (score: 1)” to “extremely satisfied (score: 7).” Therefore, the total score ranged from 3 to 21, meaning that a score between 3 and 6 indicated “low levels of PSA,” a score between 7 and 12 indicated “average levels of PSA,” and eventually, a score higher than 12 indicated “high levels of PST.” To determine the reliability of this tool, the internal correlation was calculated using Cronbach's alpha coefficients, which ranged from 0.78 to 0.85 (39, 40). Furthermore, the KPSS had acceptable validity, as it has been utilized in many studies (41–43).
The RSDCD consisted of 35 items along with 5 factors: “aggression,” “irresponsibility,” “deception,” “vandalism,” and “insufficient interpersonal relationships.” The scoring method of the RSDCD was in the form of a 5-point Likert scale for the options of “never (score: 1),” “rarely (score: 2),” “sometimes (score: 3),” “often (score: 4),” and “always (score: 5).” The total score of the RSDCD ranged from 35 to 175, meaning that a higher score indicated a more severe CD, while a lower score indicated milder CD. To determine the reliability of the RSDCD, the internal correlation was calculated using Cronbach's alpha coefficients, which was 0.97 (44). The construct validity of this questionnaire was calculated using the correlation test between this questionnaire and the “Child Symptom Inventory-4 (CSI-4),” which was 0.87 (45).
Eventually, the validated Persian versions of the mentioned tools have been implemented in various Iranian studies (45–48).
- Statistical analysis:
In order to analyze the data obtained from the current research, descriptive statistics have been considered to calculate the “mean,” “standard deviation,” “absolute frequency,” and “percentage frequency” for sociodemographic and clinical variables. In addition, inferential statistics have been implemented to evaluate the correlation between the variables of PSA, PST, and the severity of CD using the “t-test” and the “Pearson correlation coefficient test.” Furthermore, the “Spearman's correlation coefficient test” has been employed to specify the correlation between the sociodemographic characteristics and the variables of PSA, PST, IPST, and the severity of CD. In addition, Bayesian regression analysis was used to investigate the mutual correlation and predictive power between PSA, PST, IPST, CD severity, and other demographic characteristics in the form of a comprehensive network of causation relationships and correlations among the mentioned variables. Ultimately, the obtained data were analyzed using SPSS version 26 software, with both the test error rate and significance level set to be less than 0.05.
- Ethical considerations:
The present study was approved by the SBMU Research Ethics Committee, and subsequently, the ethical code (IR.SBMU.RETECH.REC.1401.818) was received. Based on this, adherence to the ethical principles of “voluntary participation,” “withdrawal permission,” “providing information,” and “confidentiality” has been considered to the greatest extent throughout all stages of the present study. Furthermore, it should be noted that written informed consent was obtained from all participants.
