        <p>Objective: Informal care, defined as the unpaid care provided to an older, frail or ill person, by a person such as a spouse, parent, child, other relative, neighbour, friend, may lead to stress, burden and low well-being levels. As the phenomenon of informal care is growing, there is a need of psychological interventions in order to support informal caregivers. Evidence-based psychological treatments obtained good results in terms of well-being, but access to these treatments could be difficult for caregivers due to the of lack of time and financial strains. Internet-based interventions could be a possible solution within this scenario. "SOSteniamoci", an Internet-based Cognitive Behavioral Treatment program, consisting of 8 modules, will be adapted and tested in Italy. Methods: A randomized controlled clinical trial involving 128 informal caregivers will be conducted. Participants will be recruited from the Istituto Auxologico Italiano IRCCS1 and social media advertisements. After initial screening they will be randomly assigned to either an experimental group or a waiting list group. Expected results: During the last decade, internet-based cognitive behavioral interventions have been developed and tested. This therapeutic approach, due to its characteristics, could be beneficial in supporting informal caregivers. We expect this intervention to be feasible and efficient in reducing caregivers' burden, anxiety, depression and stress, while improving caregivers' quality of life and the quality of relationship with the care receiver.</p>

      <title>1.1. The Caregiving Phenomenon: Changing Perspective for Future Interventions</title>
      <p>Data suggest that 80% of all long-term care in Europe is provided by informal carers
[1]. Informal care is defined as the unpaid care provided to an older, frail or ill person,
by a person such as a spouse, parent, child, other relative, neighbor, friend or other
nonkin [2]. The phenomenon of providing informal care is growing, also due to the fact
that the population ages and the prevalence of chronic illnesses is increasing as well
[36], while hospitalizations are shorter [3, 7]. The available estimates of the number of
informal caregiver ranges from 10% up to 25% of the total population in Europe.
National Alliance for Caregiving and AARP (2015), in the United States, estimated that
56% of caregivers are currently caring for someone. Among these caregivers, 85% are
caring for a relative, whereas 15% for a friend, a neighbor or other non-relative. The
estimate number of caregivers who are providing care for a parent (or parent in law) is
49%, while 12% of the caregiver population takes care of their spouses. Data reports
that informal caregivers invest an average of 24.4 hours per week providing care,
investment that increase for those caring for a spouse or a partner (45 hours per week)
[3]. Since around 80% of the total assistance provided to non-independent people in
EU is provided by informal caregivers, this estimation makes them an essential element,
the backbone, of the care provided to non-autonomous people in Europe [8]. Thus, the
growing number of caregivers have made caregiving a public health issue [9].</p>

      <title>1.2. Caregiving Burden and the Resulting Need of Interventions</title>
      <p>
        According to the evidence-based literature, informal caregiving may be experienced as
stressful and it is often associated with a number of psychosocial and health
consequences as well as financial strains, that could lead to caregiving burden [10, 11].
Caregivers’ burden can be defined as a multidimensional condition consisting of
physical, psychological, emotional, social and financial stressors linked with the
caregiving experience [12, 13]. In addition, due to their immense caregiving
responsibilities, many caregivers report on physical exhaustion [14]and even on poor
health ramifications as greater cardiovascular reactivity [15] and poor immune
response; [16]. One possible explanation for these findings is that when one's
commitment to the care-receiver becomes the priority, caregivers’ medical need may
go unattended or neglected [17], even if many caregivers recognize that the more care
they provide to themselves the more efficient they would be toward their loved ones
[18]. As it has already stated, the caregiving condition could be hard to stand for those
who are taking care of a loved one. Within this context, different interventions have
been developed in order to ease caregivers’ stress and help them better cope with their
condition. Apart from the practical support, known as respite care, that consists
alleviating the caregiver from his/her duties for a while letting someone else taking care
of the care recipient [
        <xref ref-type="bibr" rid="ref34">19</xref>
        ], it is possible to divide caregivers' interventions into three
categories: 1) Information and educational interventions; 2) Psychosocial support
interventions to reduce stress and burden; and 3) Self-care interventions that promote
caregivers’ physical health [20]. Self-care interventions, specifically, aiming at
promoting caregivers' physical health, are quite rare, yet studies showed that overall,
they produce a decrement in the level of stress experienced by caregivers and an
increment in terms of their quality of life [21].

      <title>1.3. Internet-based interventions for caregivers: using technology in order to fulfil caregivers` needs.</title>
      <p>Due to the particular conditions that characterized caregiving phenomenon, such as
financial strain, geographic constraints and the lack of time, internet-based
interventions could be a possible solution in order to help caregivers and their
relationships. Data from the literature reports that within the context of cancer patients,
couples refused to take part of the interventions because of the lack of time [18] and
because they were living too far from the intervention facilities [22]. In the same vein,
higher attendance to home-based programs by caregivers (i.e. telephone counseling or
technology-based interventions) has been demonstrated [23]. It seems necessary to
think about something that could be efficient and feasible at the same time. The
integration of dyadic interventions and technology could be useful due to it being more
feasible and cost effective.</p>
      <p>During the last decades, technology took part in our daily life and it is becoming the
new goal standard also in the clinical field and health systems [24, 25]. Evidence from
the literature show that thanks to internet-based interventions it is possible to reach
patients from a distance [26].</p>
      <p>Evidence also shows that internet-delivered cognitive behavioral therapy (ICBT) can
be as effective as other treatment formats [27], so it can be complementary or even an
alternative to face-to-face treatments [28], reducing geographical barriers both between
the partners and the therapist. These interventions would be particularly useful and
efficient in order to fill gaps due to caregiving condition, as they suit caregivers’ needs
in term of lack of time and money.</p>
      <p>Data from the literature showed that internet-based interventions have small to
moderate beneficial effect on caregivers’ mental health, including reduction of
depression, stress and anxiety [29]. Moreover, Web-based intervention programs seem
to be beneficial in terms of self-efficacy, self-esteem and strain of caregivers of adults
with chronic conditions [30]. Another review conducted on caregivers and
internetbased interventions demonstrated that those can reduce depression and burden in
caregivers, and increase self-efficacy and sense of competence, coping skills and
strategies and quality of life [31].</p>
      <p>This intervention aims at evaluating the efficacy of an internet-based intervention,
culturally adapted from the Lithuanian context, for informal caregivers in Italy.
Particularly, it will focus on reducing level of stress, depression and anxiety, improving
the level of quality of life and quality of the relationship. It will be based on cognitive
behavioral therapy and it will consist of 8 modules. These are the themes, as listed
chronologically: Introduction, Thoughts, Stress and relaxation, Problem Solving,
Communication, Anxiety, Behavioral Activation, Maintenance. These themes were
chosen after considering topics which might be the most useful for someone in a role
of an informal caregiver, considering the trans-diagnostic nature of the intervention.
The impact of the intervention will be compared against a wait-list control group.

      <title>2.3. Measures</title>
      <p>2 The Istituto Auxologico Italiano IRCCS is one of the main Italian research sites, with four main
hospitals and many clinical units located in northern Italy.
Primary outcome:
Caregiver Burden Inventory (CBI) [ Time Frame: Pre-treatment, week 4, week 8- and
12-month post-treatment]
This measure is used to evaluate caregiver burden. CBI contains 24 questions that are
distributed within 5 facets - Time Dependency, Emotional Health, Development,
Physical Health and Social Relationships. Answer options are presented on a 5-item
Likert scale and ranges from from 0 ('Never') to 4 ('Nearly Always'). Total score on
CBI is summed up and ranges from 0 to 96, higher score indicating higher levels of
burden experienced.</p>
      <p>Secondary outcomes:
1. Perceived stress scale (PSS-14) [32][ Time Frame: Pre-treatment, week 8 and 6
months post-treatment]
Measure will be used to evaluate levels of experienced stress. It contains 14
questions on a Likert scale ranging from 0 ('Never') to 4 ('Very Often'). Higher
score indicates more severe symptoms.
2. The Patient Health Questionnaire (PHQ-9) [33][ Time Frame: Pre-treatment,
week 8 and 6 months post-treatment]
Measure will be used to evaluate depressive symptoms. It contains 9 questions that
must be responded to by choosing an answer from 4-item Likert scale, where
number 0 indicates 'Not at all' and 3 - 'Nearly every day'. Higher score indicates
more severe symptoms.
3. Generalized anxiety disorder (GAD-7) [34][ Time Frame: Pre-treatment, week 8
and 6 months post-treatment]
Measure will be used to evaluate caregiver anxiety. GAD-7 contains 7 questions
that must be responded to by choosing an answer from 4-item Likert scale, where
number 0 indicates 'Not at all' and 3 - 'Nearly every day'. Higher score indicates
more severe symptoms.
4. World Health Organization (WHO-5) [35] [ Time Frame: Pre-treatment, week 8
and 6 months post-treatment]
This questionnaire contains 5 statements regarding individual's well-being. Each
of the statements must be evaluated using 6-item Likert scale with a score of 0
indicating 'At no time' while a score of 5 - 'All the time'. Higher score indicates
higher well-being.
5. Couples Satisfaction Inventory (CSI-4) [36] [ Time Frame: Pre-treatment, week 8
and 6 months post-treatment]
This questionnaire contains 4 statements regarding couple satisfaction. Each of the
statements must be evaluating using 6-item Likert scale. Higher score indicates
higher couple satisfaction.</p>
      <p>The questionnaire will be translated and back translated into the target language
(Italian) based on its original English version in order to ensure that the wording is
appropriate. This will be done in line with the recent recommendations of Swami
and Barron (2018). Moreover, it will be adapted to different kind of relationship
between caregiver and care receiver, not only spousal relationships.</p>

      <title>Intervention</title>
      <p>Behavioral: Intervention group
Intervention based on cognitive
behavioural therapy principles and
culturally adapted to Italian population.</p>
      <p>Intervention's main purpose is to reduce
caregiver burden and increase quality of
life and relationship. Intervention
contains psycho-educational elements as
well as examples and exercises.
Opening the website, participants will be provided with information on inclusion and
exclusion criteria, as well as the registration process, management and research team.
After participants provide informed consent on a secure study website, they will be
asked to complete the screening questionnaires. Participants will then be invited for a
telephone interview. Following telephone interviews, the final decision on participation
in the study will then be discussed jointly and agreed by the two co-authors (MS and
GP). The decision on exclusion or inclusion in the study will be communicated to
participants within a few days. After randomization, participants in the intervention and
wait-list control groups will be provided with information about the start of the
intervention. Participants in the Waiting-list control group will also be told that they
will be able to receive access to the same treatment once the intervention group is
finished.</p>
      <p>A secure online iterapi platform [37] will be used for communication between
therapists and participants, the distribution of program materials and the collection of
evaluations. The participant's personal information will be made anonymous by
assigning each participant a code, which will then be used to access the program. The
included participants will also be able to extend their data security by receiving the code
on their phone numbers. Code that must be entered at each time they log in, after their
self-generated password.</p>
      <p>At the beginning of the intervention, all participants will receive an email containing
their username and a personalized link to create their password. Throughout the
program, participants received an email every Thursday indicating the availability of
the new material. Participants who do not view the week's material or have not
conducted exercises will receive a weekly reminder. The memo will contain a short
encouraging message and will be sent on Monday, from therapists to participants in
their groups.</p>

    <sec id="sec-10">
      <title>2.5. Randomization procedure</title>
      <p>All participants will be randomly assigned to the Experimental or Control group. The
randomization scheme will be generated using the Web site Randomization.com
(http://www.randomization.com). Randomization will occur after the baseline
measurements.</p>

    <sec id="sec-11">
      <title>2.6. Sample size calculation</title>
      <p>
        The minimum sample size required to conduct this study was computed by using an
apriori sample size calculator (G*Power 3.1.9.2 software) for Fisher f’s tests [
        <xref ref-type="bibr" rid="ref43">38, 39</xref>
        ].
Participants will be measured with at three time points: (1) at treatment beginning, (2)
at the end of the treatment, and (3) at six months follow-up. Treatment condition
(experimental group vs. control group) was classified as between-group variable, and
time was classified as within-group variable. The a-priori partial η2 was set to assume
a value of 0.020 – small effect size [40] – that provides a Cohen’s f equal to 0.143.
Moreover, the Type I error (α) rate was set at 0.05 (two-sided) and the Power (1 - β)
was set at 0.80, according to general guidelines [40]. The a-priori correlation between
repeated measures was set at 0.20 – small correlation [40]. Finally, sphericity was
assumed. Results showed that there is an almost 80% chance of correctly rejecting the
null hypothesis of no significant effect of the interaction with 64 subjects per group for
a total of 128 participants.
