Introduction
Background
Grief is a universal experience, an emotional response to loss that is profoundly personal
and deeply affecting. While the journey through grief is unique for each individual, most
people gradually find a way to adjust to life without their loved one. However, for some, the
process becomes stalled, leading to what is known as prolonged grief disorder (PGD).
Characterized by intense longing, preoccupation with the deceased, and persistent inability
to engage with life, PGD can significantly impair an individual's functioning and well-being.
The transition to university represents a critical developmental period for young adults,
marked by new challenges, opportunities for growth, and, at times, the experience of loss.
University students are in a unique socio-emotional and developmental stage, navigating the
complexities of adulthood while often living away from their traditional support systems. The
impact of grief during this period can be particularly profound, potentially affecting
academic performance, social relationships, and overall mental health. Despite its
significance, the specific needs and experiences of grieving university students have
received limited attention in the literature.
Istanbul, a city with a rich history and diverse cultural tapestry, serves as a vibrant
backdrop for this study. Home to numerous universities and a large student population,
Istanbul offers a unique setting to explore the effects of prolonged grief within an urban
context. The city's dynamic environment, coupled with the stresses associated with academic
life, may influence how grief is experienced and processed by university students. Moreover,
cultural factors specific to Turkey may shape the grieving process, including societal
attitudes toward loss and mourning practices, underscoring the importance of contextually
grounded research.
In response to these considerations, the present study aims to investigate the effectiveness
of two therapeutic interventions, Ericksonian hypnotherapy and CBT, in treating prolonged
grief among university students in Istanbul. This research not only addresses a significant
gap in our understanding of grief interventions for young adults but also contributes to the
broader discourse on mental health support within academic settings. By focusing on this
population and setting, the study endeavors to offer insights that can inform targeted,
culturally sensitive approaches to supporting grieving students, ultimately enhancing their
well-being and academic success.
Rationale
Prolonged grief disorder represents a profound, persistent form of bereavement, distinct from
normal grief and major depression, that can significantly impair an individual's functioning.
CBT has established efficacy in treating a wide range of psychological disorders, including
prolonged grief. It operates on the premise that changing maladaptive thoughts and behaviors
can lead to improved emotional states. CBT's structured, problem-focused approach has been
widely researched and applied in various cultural contexts, including Turkey. However,
despite its proven benefits, not all individuals respond to CBT, highlighting the need for
alternative therapeutic options.
Ericksonian hypnotherapy, developed by Milton H. Erickson, offers a contrasting approach to
traditional psychotherapies by utilizing the power of indirect suggestion, metaphors, and
storytelling to facilitate change. Unlike the directive techniques of CBT, Ericksonian
hypnotherapy emphasizes the unique inner resources and unconscious mind of each individual,
allowing for a more personalized therapeutic experience. This approach aligns well with the
developmental stage and cognitive flexibility of university students, who are often more open
to exploratory and experiential forms of therapy. Moreover, the symbolic and metaphorical
nature of Ericksonian techniques may resonate deeply within Istanbul's culturally rich
context, potentially offering a more culturally sensitive approach to grief therapy.
The need to explore Ericksonian hypnotherapy in comparison to CBT for treating prolonged
grief stems from several considerations. First, the varying therapeutic mechanisms between
Ericksonian hypnotherapy and CBT suggest that they may differentially affect the grieving
process, with implications for treatment personalization. Second, the comparative
effectiveness of these therapies for prolonged grief remains under-researched, particularly
within university settings and specific cultural contexts. Finally, understanding the
potential benefits of Ericksonian hypnotherapy can broaden the repertoire of effective grief
interventions, offering clinicians and counselors more tools to support grieving individuals.
Given these considerations, this study seeks to fill a critical gap in the literature by
comparing the effectiveness of Ericksonian hypnotherapy and CBT in alleviating symptoms of
prolonged grief among university students in Istanbul. By doing so, it aims to contribute
valuable insights into the adaptability and utility of these therapeutic approaches,
enhancing the psychological well-being and academic success of grieving students.
Objectives
The primary aim of this randomized non-clinical controlled trial is to evaluate and compare
the effectiveness of Ericksonian hypnotherapy and CBT in addressing symptoms of prolonged
grief among university students in Istanbul. This comparison seeks to achieve several key
objectives:
1. Assess the Reduction in Prolonged Grief Symptoms: To quantitatively measure and compare
the reduction in symptoms of prolonged grief among participants, as evaluated by the
Prolonged Grief Scale, following the completion of Ericksonian hypnotherapy and CBT
interventions. This objective seeks to identify which therapeutic approach is more
effective in alleviating the core symptoms of prolonged grief.
2. Evaluate Changes in Associated Psychological Symptoms: To examine and compare the impact
of Ericksonian hypnotherapy and CBT on associated psychological symptoms, including
depression and overall psychological distress, as measured by the Beck Depression
Inventory and Prolonged Grief Scale, respectively. This objective aims to understand the
broader psychological benefits of each therapy in treating prolonged grief.
3. Investigate Participant Engagement and Satisfaction: To assess and compare participant
engagement and satisfaction with Ericksonian hypnotherapy versus CBT, incorporating
participant feedback and session attendance rates. This objective is important for
evaluating the acceptability and feasibility of both therapeutic approaches among
university students.
4. Explore Cultural and Contextual Factors: To explore how cultural and contextual factors
inherent to the student population in Istanbul may influence the effectiveness and
reception of Ericksonian hypnotherapy and CBT for prolonged grief. This objective
recognizes the importance of cultural sensitivity in psychological interventions and
aims to provide insights into tailoring therapies to specific populations.
Methodology
Study Design This research employed a randomized controlled trial design to evaluate the
effectiveness of Ericksonian hypnotherapy versus CBT in treating prolonged grief among
university students in Istanbul. The study aimed to recruit 150 volunteers who had
experienced loss and exhibited symptoms of grief. To ensure participants did not present with
other significant psychological symptoms that could confound the results, the SCL-90 Symptom
Checklist was utilized alongside the Prolonged Grief Scale and the Beck Depression Inventory.
Participants Participants were university students in Istanbul who volunteered for the study,
meeting the inclusion criteria of having experienced a significant loss and showing symptoms
of prolonged grief as assessed by the Prolonged Grief Scale. Exclusion criteria included
undergoing psychotherapy during the past year, significant psychological disorders as
identified by the SCL-90, and inability to commit to the full duration of the study. After
initial screening, 39 participants who scored high on the Prolonged Grief Scale were selected
and randomly assigned into three groups: Ericksonian hypnotherapy, CBT, and a waiting list
control, with 13 participants in each group.
Interventions The Cognitive Behavioral Therapy (CBT) intervention for prolonged grief was
carefully structured into an 8-session manualized program, tailored to address the
multifaceted nature of grief among university students. Initially, participants were
introduced to the CBT model of grief, focusing on understanding the relationship between
thoughts, feelings, and behaviors in the context of their loss. Key components included
identifying and challenging maladaptive thoughts related to the loss, employing gradual
exposure to avoided situations, and developing coping strategies for managing intense
emotions and fostering resilience. Special emphasis was placed on rebuilding meaningful life
activities and social connections, acknowledging the loss while encouraging engagement with
life's ongoing demands.
Ericksonian hypnotherapy provided an alternative approach, with 8 sessions designed to
harness the power of indirect suggestion, metaphors, and personal storytelling to navigate
the complexities of prolonged grief. Early sessions focused on establishing a therapeutic
alliance and utilizing personal strengths and inner resources. Techniques such as guided
imagery were used to facilitate a healthy connection with the symptoms, fostering a sense of
peace and acceptance. Subsequent sessions aimed to reframe the loss, integrating it into the
individual's life narrative in a way that honored the past while promoting openness to future
possibilities. This approach sought to cultivate a sense of personal growth and resilience,
emphasizing the individual's capacity to find meaning and continue moving forward.
Both interventions aimed to provide a supportive and healing environment, addressing the
specific challenges of prolonged grief within a university student population. The CBT group
worked on concrete skills for tackling the cognitive and behavioral aspects of their grief,
while the Ericksonian group delved into the subconscious to elicit change through more
symbolic and imaginative processes. Despite their methodological differences, both therapies
shared the goal of mitigating the pain of prolonged grief and empowering students to adapt
more healthily to their loss. Participants in the waiting list control group were offered
information on available grief counseling resources upon conclusion of the study, ensuring
they too had access to support.
Data Collection and Measures Data were collected at three time points: before the start of
the sessions, after the fourth session, and immediately after the eighth and final session.
The Prolonged Grief Scale and Beck Depression Inventory were administered at each time point
to assess changes in grief intensity, depressive symptoms, and overall psychological
distress, respectively.
Measurement Tools Prolonged Grief Scale (PGS): The Prolonged Grief Scale is a specialized
instrument designed to assess the symptoms and severity of prolonged grief disorder (PGD)
among individuals. This scale consists of items that measure the core symptoms of PGD,
including persistent yearning for the deceased, difficulty accepting the death, a sense of
disbelief regarding the loss, and marked emotional pain related to the bereavement. Each item
is rated on a Likert scale, allowing for a quantifiable measure of grief intensity. The
reliability and validity of the PGS have been established in various populations, making it a
robust tool for identifying individuals suffering from PGD (Prigerson et al., 2021).
Beck Depression Inventory (BDI): The Beck Depression Inventory is a widely used 21-item
self-report inventory measuring the severity of depression in adolescents and adults. Each
item corresponds to a specific symptom or attitude related to depression, such as sadness,
pessimism, feelings of failure, and dissatisfaction with life. Respondents are asked to rate
how they have felt over the past two weeks on a four-point scale ranging from 0 to 3, with
higher scores indicating more severe depressive symptoms. The BDI's reliability and validity
are well-documented, making it a valuable tool for assessing depressive symptoms in
conjunction with grief (Beck et al., 1987).
SCL-90 Symptom Checklist: The SCL-90 is a 90-item self-report symptom inventory designed to
reflect the psychological symptom patterns of community, medical, and psychiatric
respondents. It measures nine primary symptom dimensions, including depression, anxiety,
hostility, and paranoid ideation, and provides an overall index of distress, the Global
Severity Index (GSI). Each item is rated on a five-point scale of distress, from "not at all"
to "extremely." This tool allows for the comprehensive assessment of a range of psychological
symptoms and distress levels, ensuring that participants do not have significant comorbid
psychological conditions that could influence the study's outcomes (Derogatis & Unger, 2010).
Data Collection Process Recruitment and Screening: Potential participants were recruited
through university networks and advertisements, targeting students who had experienced a
significant loss. Interested volunteers underwent a preliminary screening using a SCL-90 to
confirm eligibility based on the study's inclusion and exclusion criteria. This included
assessing their grief experience, previous therapy, and any psychological disorders.
Baseline Assessment: Eligible participants completed the Prolonged Grief Scale and Beck
Depression Inventory as part of the baseline assessment. These tools were administered in a
controlled environment to ensure confidentiality and reduce potential biases. The baseline
data collection aimed to establish initial levels of grief, depression, and psychological
distress among participants, serving as a reference point for subsequent analyses.
Randomization and Group Assignment: Following baseline assessment, participants were randomly
assigned to one of three groups: Ericksonian hypnotherapy, CBT, or waiting list control.
Randomization was performed using a computer-generated sequence to ensure equal distribution
of participants across the groups and minimize selection bias.
Intervention and Follow-up Assessments: Participants in the Ericksonian hypnotherapy and CBT
groups attended 8 sessions of their respective therapies. Data were collected again after the
fourth session and immediately after the eighth session using the same measurement tools
(PGS, BDI). This repeated measurement allowed for the tracking of changes in grief and
depression over the course of the interventions.
Data Handling and Analysis: All collected data were coded and entered into a secure database
for analysis. Participant confidentiality was maintained throughout the study, with personal
identifiers removed or anonymized. Data analysis focused on comparing pre- and
post-intervention scores within and between groups, assessing the effectiveness of
Ericksonian hypnotherapy and CBT in reducing symptoms of prolonged grief and associated
psychological distress.
Statistical Analysis Data analysis was performed using SPSS software. Descriptive statistics
were employed to characterize the sample demographics and baseline measures. The primary
analysis involved comparing the pre- and post-intervention scores within and between the
treatment and control groups using repeated measures ANOVA, followed by post hoc comparisons
to identify specific differences. Effect sizes were calculated to determine the magnitude of
the interventions' impacts. Significance levels were set at p < 0.05 for all tests.
Ethical Considerations The study was approved by the Institutional Review Board (IRB) of
İstanbul Nişantaşı University No: 2023/2, ensuring that it met ethical standards for research
involving human participants. Informed consent was obtained from all participants,
emphasizing the voluntary nature of participation, the confidentiality of their responses,
and their right to withdraw from the study at any time without penalty.
