1. Introduction
Suicide represents a very important issue in public health. Our research departs from previous research recommendations [
1], and we tried to develop an instrument to achieve a better understanding about the attitudes towards suicide.It is estimated that in 2015 there were about 788,000 deaths caused by suicide [
2]. In Europe, previous research has shown that suicide rates range from 30.8 per 100,000 inhabitants to 2.2. One of the problems around suicide is that few identified antecedents can help the prevention, as well as its relationships with other health-related problems, such as alcohol consumption [
3].
Specifically, suicide is the main non-natural death cause in Spain [
4]. It overcame traffic accidents as the main non-natural death cause in 2007 and is committed more frequently by men. However, recently women’s suicide has risen as well. One of the main difficulties around tackling suicide is that it is frequently silenced [
5]. Among the efforts invested in prevention and the early detection of this problem, there have been different risk factors identified. Particularly in teenagers [
6], risk factors such as adverse events, sexual and psychological abuse, psychiatric problems, impulsivity, parental suicide-bereavement, and hopelessness have been found [
7,
8].
In this line, recent studies have stated the need for more and wide research that helps to shed light and understand this public health problem [
2]. In this connection, recent research has included mass media analysis, finding that there was a relationship between internet search topics and suicide [
5]. Moreover, other research has presented predictive models of suicide based on internet searches [
9]. In this line, other researchers have found similar results [
10,
11,
12]. This is in line with previous research that highlights the influence of media reporting of celebrity suicides, which tends to increase suicide rates [
13]. Due to the multicausality of the phenomenon, recent research has pointed that suicide and suicidal behavior is a challenge for clinical, social, and theoretical fields [
13]. Our research is based upon previous research recommendations that highlighted the necessity of continuing exploring and developing ways to prevent and tackle suicide.
It has been studied that press and mass media campaigns are increasingly becoming an important factor in preventing suicide [
14]. In the 1960s, debate began around the relationships between media portrayals of suicide and subsequent suicidal behaviors [
15]. Results of this research showed that the newspaper suicide blackouts had ambiguous results. For example, some authors [
15] reported that in the seventies, media suicide blackouts showed from no impact on suicide rates to a significant lowering of the rates on females. After more than 40 years of research in the field, it seems legitimate to affirm that there is a relationship between newspaper reports of suicide and suicides. Following Pirkis’s research [
15], much is still not known about media and suicide and, furthermore, mass media are changing into a digital format. There is a scarcity of research in the field of news and attitudes, and our research aims to shed light on the relationship between these two variables.
Mass media is an important factor in changing attitudes and behaviors through the passive reception of information [
14], and some research brings to light that suicides must be reported responsibly. Surprisingly, it has been found that mass media campaigns have little to no impact on suicide or suicidal behavior [
16]. Based on previous research we can pose that suicide reporting in the press is related to suicide behavior, and suicide prevention campaigns do not show an impact on suicide levels.
Specifically, evidence has been found that relates suicide-related internet activity and some aspects of suicidal behavior. This relationship has been found strongly and consistently [
17]. The conclusions of previous research propose that suicide in news and information media may influence copycat behavior in particular circumstances [
17]. Hence, individuals may perceive suicide as a useful way of coping.
Since mass media enhance identification with authors and decrease stigma, it may sensitize individuals to understand certain situations and normalize suicide in some cases. Suicide in terminally ill patients is a highly controversial topic currently [
18] and some research has shown that above 60% of terminally ill patients support this practice. In addition, a wide section of the literature tends to focus on understanding the opinions of physicians about terminally ill patients. Some suicide research does not call for a censure of suicide in media but appeals to responsibility in the media’s presentation.
Due to this ambiguity, it is difficult to evaluate how to approach suicide in the press. Since suicide is a very controversial topic, it is very difficult to assess attitudes towards it [
1]. To solve this trouble, and for a better understanding of the phenomenon, we have developed an instrument following the previous recommendation for the evaluation of the perception of suicide utility in press [
1].
In this line, it has been shown that suicide is a very complex attitudinal phenomenon. Individuals appear to show different feelings, cognitions, and behaviors if suicide is committed by themselves, people in general, or people near to them [
19]. Based on previous research [
20], people may have a general vision about suicide legitimation. Due to this, it is necessary to understand certain cases of suicide, such as terminally ill patients. Based on the abovementioned research, we hypothesize that the attitudes towards suicide as a resource may impact the attitudes towards suicide in general, or even suicide itself. This is in line with studies that state that there is evidence that individuals with a more accepting view of suicide tend to show higher levels of suicidal ideation and have attempted suicide in the past [
21].
In suicide research, we have found that instruments are usually designed for patients or physicians, finding a lack of research on general population attitudes. Since news may reach worldwide, our research tries to fill that gap and offers an approximation to suicide attitude measurement on the general population. This may help to shed light upon the information processing carried out by readers. Our study shall be understood as a pilot study and the starting point of future research in the field.
There is a huge debate about the legalization of terminally ill patients’ suicide, and there are different opinions among the general public, physicians, and patients [
22,
23]. Previous research found that the general population and patients tend to agree with assisted suicide, while most physicians tend to oppose it [
22]. Since there is polarization on attitudes over this topic, social mass media plays a central role in these processes.
Trying to understand suicide complexity, there is a considerable amount of investigation that relates depression and suicidal behavior [
24]. Recent research has related depression and external symptoms such as substance misuse, risk-taking, and difficulties in impulse control [
25]. As depression comprises cognitive factors that may affect attitudes, it is interesting to understand how people with depressive symptomatology may respond to the perception of suicide utility in news and its attitudes toward suicide in terminally ill patients.
Having said this, and recognizing the lack of investigation in this field, the main objective of this paper is to analyze the influence of the suicide utility perception in news over the attitudes towards suicide in terminally ill patients. This relationship will be mediated by suicide legitimation and moderated by cognitive depression symptoms.
Specifically, one of the main objectives of this research is to analyze if the exposure to news that helps to understand suicide is useful or tends to increase the attitudes towards suicide in terminally ill patients.
First, we will test the psychometric properties of the scale we created ad hoc for assessing suicide utility perception. After that, we expect to find that the suicide utility perception in the press will have a statistically significant impact on positive attitudes toward terminally ill patients’ suicide (Hypothesis 1). Additionally, this relationship will be mediated by suicide legitimation (Hypothesis 2). This mediation will be moderated by depressive symptomatology (Hypothesis 3).
3. Results
3.1. Exploratory Factor Analysis
The first step that we followed was to evaluate the factorial structure of the questionnaire. For this purpose, we conducted a Kaiser-Mayer-Olkin (KMO) test, which showed adequate values for conducting the factorial analysis (0.73). Moreover, we checked Bartlett’s Sphericity test, which showed adequate values as well (χ2 (136) −543.83, p < 0.001).
The principal axis factoring procedure showed a five-factor structure. We used as criteria the eigenvalues over 1.00, and factor loadings above 0.30. Taking these criteria into account we preferred to extract a four-factor matrix because the fifth factor was composed only of one item. The factor loadings may be seen in
Table 2.
3.2. Confirmatory Factor Analysis
Having explored the factor structure of our instrument, we conducted a confirmatory factor analysis in order to find the best model to use in our research. First, we conducted an analysis with the 17 items, and we adjusted the model. We used the criteria suggested by Awang [
29]; chi-square/df should be below 2. CFI, GFI, and NFI should be above 0.90 for a good fit, and RMSEA should be below = 0.08. We eliminated the items with lower factor loadings in the confirmatory analysis. Results of the two purposed models can be seen in
Table 3.
As can be seen, the 10-item model offers a better adjustment to the data. The statistical diagram may be seen in
Figure 1.
Having analyzed our model, it yields good enough indexes for using it in our research, guaranteeing its reliability. Cronbach’s alpha remained 0.85.
For testing our hypotheses, we conducted a moderated mediation model developed by Hayes [
30]. Concretely, we utilized model 7 of his PROCESS macro for SPSS. The first step for conducting a moderated mediation analysis is to weight the correlation between variables. Age, gender, academic level, and press reading frequency did not show any significant relationships. Due to this, they were not included in the final model. The correlation matrix may be seen in
Table 4.
The PROCESS macro is based on a bootstrapping procedure that extracts 1.000 random samples for assessing the hypotheses. For a better explanation, we will expose direct relationships, simple mediation, a simple moderation model, and mediated moderation indexes.
3.3. Direct Relations and Simple Mediation
The first step of our model is to assess the influence of the suicide utility perception over the positive evaluation of terminally ill people euthanasia. We found that this direct relationship was statistically significant (B = 0.72; SE = 0.17; 95% CI (0.36; 1.07), p < 0.001. As such, we have enough evidence to accept hypothesis one. In order to continue with our model, we will test other direct relations. Suicide legitimation was significantly related to the positive evaluation of terminally ill people euthanasia (B = 0.68; SE = 0.08; 95% CI (0.53; 0.84), p < 0.001). When evaluating the influence of our variables on suicide legitimation, we found that neither the suicide utility perception (B = − 0.50; SE = 0.79; 95% CI (−2.10; 1.09), p > 0.05), nor the depression psychological concomitants (B = −2.52; SE = 1.73; 95% CI (−5.99; 0.95), p > 0.05) were statistically significant. However, we found that the simple mediation (utility perception -> legitimation -> terminally ill people euthanasia) model was supported by our data (B = 0.58; SE = 0.19; 95% CI (0.19; 0.97)). Having said this, we have enough evidence to confirm hypothesis 2.
3.4. Moderation Analysis
The simple moderation analysis (utility perception impacts on suicide legitimation, being these relationships moderated by depression psychological concomitants) showed not statistically significant values (B = 0.78; SE = 0.45; 95% CI (−0.13; 1.69), p > 0.05). However, we found that at 16th percentile of depression psychological concomitants, effects were not significant (B = 0.42; SE = 0.33; 95% CI (−0.23; 1.09), p > 0.05), there were at 50th (B = 0.97; SE = 0.28; 95% CI (0.41; 1.53), p < 0.01) and 84th (B = 1.52; SE = 0.49; 95% CI (0.52; 2.51), p < 0.01) percentile.
3.5. Moderated Mediation Analysis
Lastly, we assessed the final model and confirmed it was statistically significant. Utility perception (X) was related to terminally ill subjects’ euthanasia (Y), through suicide legitimation (M), being these relationships mediated by depression psychological concomitants (W) (B = 0.53; SE = 0.31; 95% CI (0.05; 1.30)). When evaluating the conditional effects of our model we found that at lower levels of depression psychological concomitants, support for terminally ill people’s euthanasia was not significant (16th percentile; B = 0.29; SE = 0.28; 95% CI (−0.39; 0.77)). Nevertheless, while increasing the levels of depression psychological concomitants, the support for terminally ill people’s euthanasia increased as well (84th percentile; B = 1.04; SE = 0.29; 95% CI (0.51; 1.67)). Because of this, we have enough evidence to confirm hypothesis 3. A complete statistical model may be seen in
Figure 2.
4. Discussion
The main objective of this paper is to analyze the influence of suicide utility perception in news over the attitudes towards suicide in terminally ill patients. This relationship will be mediated by suicide legitimation and moderated by cognitive depression symptoms.
Since suicide represents a very important issue in public health, representing the main non-natural cause of death in Spain [
4], we found that it is necessary to address some interrogatives highlighted by previous research [
13]. Recent research has stated that being exposed to suicide news is related to copycat conduct and higher rates of suicide [
5]. Based upon this association, our research tries to find out the cognitive mechanisms that help to link suicide exposure and attitude change. Since previous research recommends continuing to explore the mechanisms around suicide, our study fills the gap, focusing on the process of subjects’ change of attitudes when exposed to suicide news.
Here is where our research represents a new field of study. Our research highlights that the perception of the utility of suicide in news is directly and significantly related to the attitudes toward terminally ill patients’ suicide. It seems that there is a change of attitudes towards the perception of suicide. This is in line with previous research that shows that suicide-related topics in the newspaper are related to a higher suicide rate. The new aspect of our research is to discover that reading about the utility of suicide does not increase the legitimation of suicide, but the approbation of terminally ill patients. There is not a general change of attitudes towards suicide, but future research should explore if this change of attitudes is related to empathic processes. Previous research has shown that suicide is a very complex attitudinal object and must be investigated deeply [
20]. It would be interesting to test if the perception of suicide utility on the press may impact one’s own suicidal tendencies. Since it is a very complex and ethically compromised topic, future research should find a way to evaluate how news impacts the different types of suicide. Moreover, since suicide antecedents are not so clear and are frequently silenced [
5], our research represents a new contribution to this field. First, our research draws from previous papers where it has been said that psychological depressive symptoms are related to suicide [
8], but the innovation is that in our research these symptoms act as a moderator. Specifically, psychological depression symptoms did not show any relationship to the attitudes toward terminally ill patients, but a moderation effect. It is interesting that, in our paper, depressive concomitants are not related to suicide legitimation, even when are combined with suicide utility perception. However, when increasing the depression levels, from the 50th percentile our data showed that there is a significant relationship with terminally ill patients through suicide legitimation. Future research should explore deeper these relationships to prevent suicidal attitudes in depressive subjects. This is in line with previous research that strongly relates depression and suicide [
31].
Recent research has shown that mass media campaigns are an important factor in preventing suicide [
14], while others have shown no effect to this end [
17]. Our research contributes to understanding why it may happen that some of them have not succeeded. It seems that there are dispositional variables (such as depression) and environmental variables (such as the circumstances around suicide) that might have an impact on the attitudes towards suicide. Understanding these circumstances may enhance some favorable attitudes towards certain cases of suicide, specifically in people with depressive symptomatology. Our research matches with previous research that recommends addressing suicide cautiously and respectfully.
In line with previous research, our study finds that there is a direct relationship between the exposure to news and positive attitudes towards terminally ill patients. It seems that, based upon the findings of previous research that have found ambiguous relationships [
16], it is needed to specify the conditions when being exposed to suicide news can lead to attitudinal change. Attitudes towards suicide are a very important topic in preventing suicide. Since suicide attitude is influenced by culture, it is important to study. As previous research recommends, understanding attitudes towards suicide may be useful in suicide prevention or in providing interventions. This is in line with studies that state that there is evidence that individuals with a more accepting view of suicide tend to show a higher level of suicidal ideation and have attempted suicide in the past [
22].
Moreover, our research confirms that social media plays a very important role in attitudinal change. Based upon research that highlights that there is a division between physicians and the general population around suicide [
23], future research should investigate if exposure to suicide news has the same impact in these two different populations.
5. Limitations
Our paper has some important limitations. First, being a pilot study, the sample is not representative and is too small. This may affect the generalization of the results. Future research should extend the sample and randomize the experiment to gain validity. Secondly, the lack of established measures to assess the main variables of our study is a major limitation. Hence, we created the instrument and validated it in the same study. We believe that future research should apply validated instruments, or test the reliability of our instrument. Thirdly, future research should investigate if our findings are similar in different populations, such as physicians and the general population. In addition, there may be some differences in clinical or subclinical populations. Longitudinal studies are required to test the influence of press reading over the attitudes towards suicide over time.
Finally, our research has shown that suicide patterns do not show a significant impact on terminally ill patients’ euthanasia or suicide legitimation. However, in subjects with higher values of this variable, it seemed to appear a significant moderation of the influence of perception of utility over terminally ill patients’ suicide, through suicide legitimation. It would be interesting to replicate our research in a clinical population to test the strength of this association.
We have shown that the perception of utility in news has an important impact on suicide attitudes and news editors should be aware of this peculiarity. It is required to test the impact of this utility on suicidal tendencies. Being aware of these aspects, we could be a more responsible society, and develop models that may tackle the huge impact that suicide has all over the world.
